#774: Learnings from 1,000+ Near-Death Experiences — Dr. Bruce Greyson, University of Virginia

0:00 Hello, boys and girls, ladies and gents, this is Tim Ferris. Welcome to another episode of the Tim Ferris Show where it is my job to interview world class performers from all different disciplines to deconstruct How they do. what they do. Now in this case I wouldn't recommend replicating or attempting to replicate what some of the subjects patients case studies have experienced, which is namely dying and then being revived in some capacity. So don't do that. But my guest today is Bruce Grayson MD. He is the Chester F. Carlson Professor Emeritus of Psychiatry and Neurobehavioral Sciences and Director Emeritus of the Division of Perceptual Studies at the University of Virginia, where he has practiced and taught psychiatry and carried out research since 1995.

0:41 He's also a distinguished life fellow of the American Psychiatric Association, and his most recent book is After. A doctor explores what near-death experiences reveal about life. and beyond. He has studied, documented more than a thousand Near death experiences. And what made him appealing to me as a guest with this incredibly

1:01 unusual terrain is that he was raised with a secular what we could call rational materialist worldview. So with that introduction, I hope you enjoy this very wide ranging and unusual conversation, but first just a few words from the sponsors who make this possible. I have been fascinated by the microbiome and probiotics as well as prebiotics for decades, but Products never quite live up to the hype. I've tried so many dozens and there are a host of problems. Now things are starting to change, and that includes this episode's sponsor, Seeds DSO1 Daily Symbiotic. Now it turns out that this product, Seeds DSO1, was recommended to me

1:46 many months ago by a PhD microbiologist. So I started using it well before their team ever reached out to me about sponsorship. Which is kind of ideal because I used it unbidden, so to speak, came in fresh. Since then it has become a daily staple and one of the few supplements I travel with. I have it in a suitcase literally about ten feet from me. Right now. It goes with me. I've always been very skeptical of most probiotics due to the lack of science behind them and the fact that many do not survive digestion. to begin with. Many of them are shipped dead. DOA. But after incorporating two capsules of seeds DSO1 into my morning routine, I have noticed improved digestion and improved overall health. seem to be a bunch of different cascading effects. Based on some reports, I'm hoping it will also have an effect on my lipid profile, but that is definitely TBD. So why is CEED's DSO1 so effective? What makes it different? For one, it is a two in one probiotic and prebiotic formulated with twenty-four clinically and scientifically studied strains.

2:46 that have systemic benefits in and beyond the gut. That's all well and good, but if the probiotic strains don't make it to the right place, in other words, your colon, they're not as effective. So seed developed a proprietary capsule and capsule delivery system that survives digestion and delivers a precision release of the live and viable probiotics to the colon. Which is exactly where you want them to go to do the work. I've been impressed with CET's dedication to science backed engineering with completed gold standard trials that have been subjected to peer review and published in leading scientific journals, a standard you very rarely see from companies who develop supplements. If you've ever thought about probiotics, but haven't known where to start, This is my current vote for great gut health. You can start here, it costs less than$2 a day. That is the DSO1. And now you can get 25% off your first month with code 25TIM. And that is 25% off of your first month of Seeds DS01 at seed. dot com slash Tim. using code 25 TIM all put together. That's C dot com slash Tim, and if you forget it, you will see the coupon code on that page.

3:52 One more time. C dot com slash Tim Code. twenty five tip. As many of you know, for the last few years, I've been sleeping on a Midnight Lux mattress from today's sponsor, Helix Sleep.

4:04 I also have one in the guest bedroom downstairs and feedback from friends has always been fantastic. Kind of over the top, to be honest. I mean they frequently say it's the best night of sleep they've had in ages. What kind of mattresses, and what do you do, what's the magic juju. It's something they comment on without any prompting from me whatsoever. I also recently had a chance to test the Helix. Sunset Elite in a new guest bedroom, which I sometimes sleep in, and I picked it for its very soft but supportive feel to help with some lower back pain that I've had. The Sunset Elite delivers exceptional comfort while putting the right support in the right spots. It is made with five tailored foam layers, including a base layer with full perimeter zoned lumbar support. right where I need it, and middle lay with premium foam and microcoils that create a soft contouring feel. Which also means if I feel like I want to sleep on my side, I can do that without worrying about other aches and pains I might create. And with a luxurious pillowtop for pressure relief, I look forward to nestling into that bed every night that I use it. The best part, of course, is that it helps me wake up feeling fully rested with a back that feels supple instead of stiff. That is the name of the game for me these days. Helix offers a 100 night sleep trial. Fast free shipping and a fifteen year warranty. So check it all out. Get twenty percent off of all mattress orders by going to Helix Sleep.

5:38 No we're just seeing it. My cybernetic organism, living tissue over metal endoscellary. No Doctor Grayson, thank you for making the time today. It's very nice to meet you. Thank you, Tom. Delighted to be here with you today.

6:00 I thought we would start More or less at the beginning in terms of chronology of your life. And we're not gonna do an A B C D linear recap of your whole life because that would that would be an epic multi-day affair. But Perhaps you could tell us as a setting of the table. A bit about your childhood.

6:19 How were you raised? What did the environment foster in terms of thinking in you, frameworks for understanding the world, that type of thing. Sure, Jim. Well, I was raised in a scientific Non religious household.

6:33 My father was a chemist and as far as he was concerned. What you see is what you get. There's nothing beyond the physical. So that's how I was raised. Being a scientist He stimulated me a desire to

6:44 Gather information. And I often participate in some of his experiments. He had a lab set up in his basement. He also taught me though that If you Study things that we pretty much understand already.

6:55 You can make little inroads here and there about Five points. If you really want to make some impact. He's to study things we don't understand at all. And it gave me examples of that. So I grew up with that idea that

7:06 I wanted to be a scientist and discover new data. And try to figure out what's going on with it. Did you have At that point. An innate fear of death?

7:19 These seem like some questions that might be important to touch upon before we get into the meat and potatoes of what we'll dive into shortly. Was that inbuilt or experienced by you? Actually the answer is no. I didn't have any fear of death. Yeah, we certainly had family relatives that died. And as far as I could tell

7:38 When you die, that's the end. What's to be afraid of there? Light's out. Light out. What attracted you

7:44 Two psychiatry. your path to psychiatry from the experiments In the basement. What led you there?

7:55 Well, when I went through medical school I had no idea what I wanted to do. I kinda thought I'd be a a family doctor. But I found that When I did my psychiatry rotations. There were so many more unanswered questions.

8:07 So many things that we had no idea how to explain. Much more though with the brain than with the kidneys or the heart or the lungs. I thought This is where I need to go. To look at

8:16 What's going on in the brain to have these thoughts and ideas and feelings So I went in that direction. Were there any particular conditions that fascinated you? This is predating the anti investigations. But were there any particular conditions? I found myself

8:36 Really drawn towards psychoses. People who had Hallucinations and delusions. And just didn't think the way the rest of us do. No, most of the things that psychiatrists deal with.

8:47 Are common everyday things like anxiety, depression Which everyone has to some extent. But I really was fascinated by the more extreme conditions. Schizophrenia and manic depressive illness. People are just

8:59 A totally different Views of the world than I did. So I suppose this is his own. Good time as any. to segue into

9:10 Some of the what many would consider I think what most would consider stranger terrain. even beyond Psychosis, although that's a Pandora's box we could certainly get into quite separately. And I suppose that the Stain on the tie on the story surrounding that may make some sense to tell. Would you mind sharing that with the audience?

9:31 Sure. I I went through College and medical school With this strict materialistic mindset that The physical world is all there is. And in one of my first weeks as a psychiatric intern.

9:42 I was asked to see a patient who was In the emergency room with An apparent overdose. I was in the cafeteria half of my dinner when this call came through. And being a green intern, I was startled by the beeper going off.

9:55 I dropped my fork and spilled some spaghetti sauce on my tie. So again, being a new internet, I didn't want to embarrass myself. So I put on a white lab coat and buttoned it up so nobody could see it. I went down to see the patient. And she was totally unconscious. I could not revive her.

10:10 But there was a roommate who was who was in another room about fifty yards down the hall. So I left the patient. There was a sitter there with her as happens with all.

10:20 Suicidal patients. And I went down to see the roommate. I spent about twenty minutes talking with the roommate. Trying to understand. What was going on with a patient? What stresses did she have?

10:31 What drugs she might have taken for an overdose and so forth. It was a very hot Virginia. Late summer. Night.

10:38 And I was starting to sweat in that room. There's no air conditioning back in the seventies. So I unbuttoned my coat so I wouldn't sweat so much. Inadvertently exposing the stain on my tie. When I finished talking to the roommate, I stood up to leave and then saw that it was open, so I quickly buttoned it up again.

10:53 Said goodbye and set to our way. Then I went back to see the patient. And she was still unconscious. I confirm with the sitter who was with her. That she had not awakened at all.

11:03 During the time I was gone. She was admitted to the intens because she did have some cardiac instability because of the overdose. And when I saw her the next morning. When she had awakened she was just barely awake.

11:16 I went into a room. I said So and so I'm Doctor Grayson from psychiatry. And she opened one eye and said. I know who you are. I remember you from last night.

11:27 That just blew me away because I knew. She Asleep at best and not unconscious as it were, so I don't know how she could have known that. So I said to her.

11:36 And yeah, I'm surprised I thought you were out cold when I saw you last night. Then she opened her eye again and said. Not in my room. I saw you talking to Susan down the hall. That made no sense to me at all.

11:49 She was lying there in the gurney. The only way she could have done that is if she had left her body and come down and That made no sense. You are your body. How can you leave it? So I didn't know what to do. I thought Is she pulling my leg? What's going on here? She saw that I was confused.

12:02 And then she started telling me about the conversation I had with her roommate. What questions I asked? What? Susan's answers were And then finally said.

12:11 And you had a red stain on your tie. That just blew me away. I didn't know what to make of this. I was really getting flustered at this point. I thought were the nurses somehow with her to Check this poor intern.

12:23 But no one knew about the stain except the the room. So I realize that Yeah, I was having trouble keeping my composure then.

12:30 But My job is to deal with her mental status, not mine. Pushed into the back.

12:38 What made you Take the overdose, what are you thinking about suicide now, and so forth. I thought well I'll t I'll think about this other stu later on. So she was the manager of the psychiatric unit. And

12:50 I was a busy internet. I didn't have time to think about this stuff. I didn't dare tell anybody. They think I was crazy. So I pushed pushed it on the side and just didn't think about it for a while. But it was very, very emotionally upsetting to me to think.

13:03 This bizarre thing happened, but it it can't happen. It can't have happened. There must be some other answer to it. It just sat there in the back of my mind for about five years. Until

13:14 I was up now on the faculty at the University of Virginia. And we had a young intern join us, uh Raymond Moody. who wrote a book called Life After Life in which he gave us the term near death experiences. And describe what they were. I had never heard of this type of thing before. And when he described it to me

13:31 I realized. That's what this patient was talking about. She was talking about In a near just situation. Leaving her body.

13:38 Seeing things accurately from another location. Um I thought well I need to understand this. So I started collecting cases.

13:46 And it wasn't hard to do. These are very, very common phenomena, but nobody talks about them. But if you start asking patients who have been close to death They will tell you about them. And here I am fifty years later still trying to understand them.

13:59 Did you expect it was gonna last five decades or did you think this was gonna be a short project of collecting case studies? I assume Tim that In a couple of years I have a simple Physiological explanation for this. And

14:12 That would make me satisfied and be the end of it. But the more I learned about them. The harder they seem to understand. So I think I'm more comfortable with Not knowing all the answers.

14:23 So just a clarifying question on the Case study of this particular woman who had overdosed attempted suicide. Was that I guess based on all you know now. Or what people would consider a near death experience, an N D E.

14:41 Or Was it some close cousin? Because presumably she was not. intubated and flatlined at the point that you were talking to a roommate. She was Alive, but

14:54 either comatose or asleep or otherwise cognitively. Offline. Right. How do you think about that? Well they were measuring her heart function, her EKG. And her heart had not stopped.

15:05 She was having erratic arrhythmia. Ready. forms of of her of her heartbeat. So I don't know how close to death she was. I mean it's it's always hard to tell how close to death someone is. Whether she had a real near death experience or not.

15:18 I don't know because I didn't Investigate it. At that time. I didn't know anything about Nietzsche experiences. I didn't know what questions to ask. So I just wanted to Get out of my life and push out of the way.

15:29 So looking back on it. It's certainly not proof of anything. Except. How unnerving this was to me. Emotionally.

15:36 To have this happen. So I th I suppose that As part of Sort of investigating the overall context for thinking about these things.

15:47 It might be Useful to talk about This is, I'm sure, out of order in terms of the questions you might usually get asked, but the NDE scale. And the reason I want to ask about the NDE scale. that I believe you developed. Maybe it was in collaboration with Colleagues.

16:04 Is the High internal consistency, and maybe you can just describe these things. Split half reliability. That one I'm actually not. familiar with and then test retest reliability, which is seemingly a critical component of this. And the reason I bring all this up. As the crow flies, doesn't really need to fly. Hops.

16:22 About twenty feet away I have an Encyclopedia Britannica set that was bought by Richard Feynman when he was, I believe, forty two. And I'm gonna butcher this. paraphrase of a quote of his, but in effect, it is most important not to fool yourself and you're the easiest person to fool, I believe, is one of his quotes, right? Hence we have the scientific method, the structured way for investigating and testing hypotheses. So could you speak to the scale? And we're gonna get to other questions around The

16:52 perhaps common criticisms or forms of skepticism. Speaking to the biological underpinnings, but let's talk about the scale first, because I'm sure a lot of people listening would think to themselves, Well, number one, There have to be a lot of people who just make up stories. And they want to sell books and they do this, this, and this. Not in your case. I'm just saying those who've experienced or claim to have experienced NDEs and C and X, Y, or Z. And then there are people who would love to misrepresent and become a messia of this, that, and the other thing. So how do you make sure you're not fooling yourself or being fooled? Could you just perhaps describe The N D E scale.

17:29 Or speak to that whatever way makes sense to you. But back in the late nineteen seventies After people have read Raymond Moody's book. Several psychologists and physicians started getting interested in in studying this phenomenon.

17:43 So we assembled a meeting at the University of Virginia with about Two dozen. These people researchers who wanted to study it. And try to agree on How to do that.

17:53 And it turned out that everybody had a different idea about what a near death experience was. An out of body experience? Some thought was a sense a feeling of bliss. Some thought it was a communion with God.

18:08 All sorts of different interpretations people had. And they didn't agree on what should be included as part of a near death experience. So I surveyed A large number of researchers who have published about this And ask them to give me a little bit of a

18:22 A list. Of The most common features you see in a near death experience. I have some eighty. Features.

18:29 Which is ridiculous. Ha ha ha. So I took that list. And I gave the list to a bunch of near death experiencers. And said

18:39 Which ones of these do you think are really important in defining a near death experience? And they will lit down a bit. And I took the little down. List And gave it back to the researchers and said

18:49 Which ones of these do you think are the really important ones? And they whittled it down again and went back and forth between the researchers and the experiencers. Until I had a consistent list of sixteen features. That they all agreed. were the important parts of a near death experience.

19:04 And they included Changes in your thought processes. Making faster and clearer than ever before. Having your past flash before you. Strong feelings of emotions.

19:15 Usually Joy and bliss. And a sense of being unconditionally loved. By brilliant light. Not always, sometimes there's fear also.

19:25 So we developed the scale of these sixteen items. I've used that for the standard of deciding. Which ones of these phenomena are new to the experiences and which ones are not. It's been

19:37 Now translate into more than twenty different languages. It's been used in thousands of studies around the world. There have been attempts to refine it, to improve it. There are things we know now that I didn't know back then. And people have tried to add things to it.

19:49 But basically all the additions don't make much of a difference. You still identify the same experiences being NDEs. With or without them. So that's where it was. That's where the scale came from. Can you speak to some of the elements that might Help you separate out.

20:05 For lack of a better way to phrase it. Truexperiencers versus people who have false positives or who want to tell a story. Well, I actually published a paper about False positives. Oh yeah.

20:16 had people who claim to have any death experience. but did not score very highly on that scale. And we want to look at why they think they have new death experiences. And you're right when you said before that some people are making things up. Do they want the publicity? They want to be held as messiahs.

20:33 That's true. But I think there were a small minority of people who claimed to have near death experiences. And they're usually very easy to identify. But what they do with the experience. If you immediately go on on the talk circuit and

20:46 Talk to Tim Furris and other people like that and why brak about How enlightened you are now, we say, Well Let someone else study those something I'll deal with those. But the majority of people who I think were false positives. But people who have some

21:00 less intense form of mental illness. If people are blatantly psychotic, we don't include them in the studies. But there are people who have personality disorders. W same On the surface to be perfectly fine. But

21:12 Have. Exaggerations of our traits that that make them function differently in the world. And some do have this incredible Need to Get confirmation of what's happening to them.

21:24 They feel different and they don't know why. So the here about new jet expiration things. And think. Maybe that's why I'm different. Maybe I had a knee death experience. What we're gonna do in this conversation, and I'm just scratching my own itch from a curiosity perspective, but we're gonna bounce all over the place. I like to okay frame that as a feature, not a bug, but it's gonna be pretty

21:43 nonlinear. So I I want to zoom in and out from the clinical skeptical side too. The hopefully And I think we'll get to quite a few of these, but examples that could be

21:56 Corroborated in some fashion. And those may overlap with those that are described as out of body experiences. They might not. And we'll probably Come back to that term as well. But could you tell the story of the tell me if this is enough of a cue.

22:12 The red MGB. Yeah, many people. An initiative experience. See that they Encountered deceased loved ones in the experience.

22:21 And that can easily be explained as wishful thinking. Expectation. You know, you think you're dying. And you would love to see your grandmother once more, so She comes to you. And there's no way to prove or disprove that.

22:33 However. In some cases. The person having the near death experience encounters someone who had died. But nobody yet knew they had died. So that can't be dismissed as expectation and wishful thinking.

22:47 This is not a new phenomenon. Pliny the Elder wrote about a case like this in the first century A D But we're hearing about a lot of them now. About twelve years ago I wrote a paper that had thirty different cases. From recent years. Jack was one of those.

23:00 Yeah, an experience actually it was in South Africa back in the seventies. And he was a young Technician at that time. and had very serious pneumonia. And he basically stop breathing and have to be resuscitated.

23:12 So he was admitted to the hospital with a severe pneumonia. And he had one nurse who was constantly working with him as his primary nurse. A young Pretty girl about his age. He flirted a lot with her when he could.

23:24 And one day she told him she's gonna be taking a long weekend off. And there'd be other nurses. Substituting for her. So he Wish you well and

23:33 She went off. And Over the weekend while she was gone. He had another respiratory arrest where he couldn't breathe. He had to be resuscitated.

23:42 And during that time he had a near death experience. And he told me that He was in this beautiful pastoral scene. And there out of the woods came His nurse, Anita, walking towards him.

23:54 And he was stunned because He was in this different world. What's she doing there? So we said, you know, what are you doing here? And she said, You know, Jack. You can't stay here with me.

24:03 I want you to go back. And I want you to find my parents. And tell them that I love them very much. And I'm sorry, I wrecked the red MGB. He didn't know what to make of that, but she turned around and went back into the woods.

24:15 And then he woke up later. In his hospital bed. Now he tells me that Back in the seventies. There were very few MGBs in South Africa.

24:23 And he had never seen one. When the first nurse came into his room he started to tell her about his experience. And seeing his nurse Anita. She got very upset and ran out of the room. It turned out that she had taken the weekend off.

24:37 to celebrate her twenty first birthday. And her parents had surprised her with a gift of a red MGB. She got very excited. hopped in the car and took off for a test drive. and crashed into a telephone pole and died instantly.

24:51 Just a few hours before his near death experience. I don't see any way you could have known or wanted or expected her to have. An accident and die. There's certainly no way you could have known how she died.

25:03 And yet he did. And we've got lots of other cases like this. They're called Peak and Darien cases. Based on a book that was published in the eighteen hundreds. With cases like these.

25:13 Where people encounter deceased individuals who were not known to be dead. Yeah, I don't know how to explain those. Now just to put my skeptics hat on, I could say well. If I were Jack, was it Jack? Let's just say it's Jack. That would make one hell of a story if there wasn't a third party to

25:32 sort of independently verify it with. Right. But there are other cases and for people listening, we're gonna come back to Some of the common questions I would say forms of discussion around these related to possible biological mechanisms or lack thereof. We're gonna come back to that in a second. But there are then Cases that are

25:51 Seemingly characteristically quite different. And Perhaps can be. And I'd be curious to know if this has been done or not, but verified with third parties. And one that comes to mind that I've heard you discuss is related to the

26:07 Surgeon flapping like a bird. And I was hoping that you could Give a a description of that. particular case study. Before we get to that, how many Near death experiences.

26:20 Have you documented studied or otherwise. Read about it. put into the archives yourself. How many instances would you say you have encountered in one way or another? I've got slightly more than a thousand in my database at the University of Virginia. Where we have validated as much as we can.

26:39 that they were in fact close to death and and this is what happened to them. I've talked to many more people about their near death experience that I haven't included because I wasn't confident that they really fit the criteria for being in the study. But it's really much more common than you might think it was. Because people don't talk about these things.

26:55 You mentioned people wanting the publicity of this That is actually. Maybe More true now. But back in the seventies and eighties.

27:02 Nobody wanted to talk about these things. Yeah, seem insane. If you talk about things you got ridiculed. You got. Refer to a psychiatrist

27:10 You were called crazy. You were shunned by people you knew. Both materialist and religious folks. They didn't want to hear about these things. So people did not talk about these events. And what of this surgeon flapping like a bird?

27:23 Yeah. A fellow Al in his mid fifties. Was a van driver. And he's out on his rounds one day. Yeah, he had

27:33 Chest pain. And he knew enough to stop his rounds and drive to the The emergency room. And they did some evaluations and found that he had four arteries to his heart. That were blocked.

27:44 And they wish him to the emergency one for Uh urgent. quadruple bypass surgery. So he's lying on the table. Fully unconscious.

27:54 The drapes over and so forth. And he tells me that in the middle of the operation He rose up out of his body. And look down. And saw

28:02 The surgeons operating home. And he saw the chief surgeon who he hadn't met before. Flapping his arms like he was trying to fly. And he demonstrated for me. At that point I left.

28:14 So thought. This is obviously a hallucination. Doctors don't do that. But he insisted that I Check with the doctor, he said, This really happened. Ask him.

28:23 So he told me lots of other things about his near death experience, but that's the one that I was able to verify. So I talked to a surgeon. Who w actually have been trained in Japan. And he said.

28:34 Well yes, I did do that. I have a habit. Of Letting my assistants start the procedure. Well I put on my sterile gown and gloves and wash my hands and so forth.

28:45 Then I go into the operating room and watch them for a while. 'Cause I don't want to risk touching anything with my sterile hands now. I point things out to them with my elbows. And point to things out. Just the way

28:57 Al was saying he was trying to fly. I don't know any other doctor that's done that. I've been a doctor for more than fifty years and I've never seen anyone do that. So it's kind of an idiosyncratic thing. Uh is there any way.

29:09 I could have seen that while he was totally anesthetized. He had his heart. Was open. I don't think there's any way you could have seen that. And yet he did. All right. So

29:18 So many questions. And let's start with The question of How rational materialist skeptics and that's not meant as a criticism of those people at all.

29:32 might try to explain this. They might say it is a lack of oxygen or a diminishing amount of oxygen. It might be a cascade of neurotransmitters that are released when A B or C happens. It might be the introduction of drugs. I certainly know when I've had surgeries never said or God knows what else introduced to my bloodstream. Some very strange things happen. Although I haven't experienced the type of thing you're describing when I've been anesthetized. How do you respond to those or how do you think about those?

30:01 Explanations. I'm sympathetic with them, but you know, I started out as a materialist skeptic. After fifty years I'm still skeptical. I'm no longer a materialist, I think. That's a that's kind of a dead end when it comes to explaining a near death experience as another phenomena like this.

30:17 When I started out, I assumed Okay, we'll look at Things like Heart rate. Oxygen level.

30:22 Drugs given and so forth. And each thing we try to study. Turn out not to explain anything. For example, The most obvious thing was the lack of oxygen because no matter how you come close to death That's the last common denominator, you're gonna lose oxygen to the brain.

30:37 But when you actually study this. What you find is that people who have near death experiences actually have a higher oxygen concentration than people in similar situations who don't have any death experience. Could you say more about that? How do we know this or how do we surmise that?

30:53 They don't measure what's going on in the brain, but they measure In the peripheral blood system. how much oxygen is flowing through. Okay, with a pulse oximeter or something like that. Yes. In a hospital setting. Okay. They also can draw blood and measure measurement more directly than at the pulse ox. But what they find is that when they draw blood from people who were in a near death situation

31:11 Those who have a near death experience have a higher oxygen level for those who don't. So What that means is that Lack of oxygen is not causing the experience.

31:20 In fact it seems to be inhibited in some way. And what that mean may be that Many people have any death experience. But if you're Lacking oxygen.

31:28 You can't remember it later on. And then only if you have good enough oxygen. Do you remember it later on? So maybe related more to the memory of the experience than the experience itself. Likewise, with people given drugs as they're approaching death.

31:41 The more drugs you're given, the less likely you are to report on your death experience later. Yeah, there are some drugs. That can mimic. parts of a new death experience. The narcose that are given to dying patients. But things like ketamine.

31:54 various psychedelic drugs, people using psilocybin now. And they can produce things that mimic in some ways some features of new death experiences. They don't produce the whole phenomenon. They don't, for example. reliably have the blissful feelings

32:09 And they certainly don't have the accurate out of body perceptions that many near death experiencers have. I should say that Jam Holden at the University of North Texas Studied. About a hundred cases of

32:20 People who claim to be out of their bodies and seeing things. And what she found when she So Third party corroboration. was that in ninety two of the hundred.

32:29 They were completely accurate. In six cases. There were Partly accurate and probably inaccurate. Only one or two were completely wrong.

32:38 So the vast majority were actually corroborated by other people. What are some other examples of hospital setting and part of the reason I mention that specifically is that you have Multiple credible witnesses. In some cases, I would imagine.

32:54 Yes. Right. Which makes it interesting because you could independently, at least in theory Verify confirm. various occurrences while a patient was sedated. Suffering from cardiac or otherwise. What are some examples that come to mind that you think are the most

33:13 Defensible. in those environments or otherwise, but where you have the ability to Independently. Confirm or have Denied.

33:23 X, Y, or Z that happened. The ones that come to mind are the ones where people see Deceased. Individuals who No one knew we had died yet.

33:31 I can give you more examples of of that. And they're often corroborated by other people. And also people who claim to leave their bodies and see things from an out of body perspective. That they shouldn't have known about. And we're not talking about seeing things like

33:43 Oh, I saw the doctor in Green Scrubs. Or I saw a dust on the lap. Something you would expect. The nurse had mismatched shoelaces. No, things that you wouldn't expect. Or the doctor flapping his wings.

33:56 We have corroboration for a lot of these cases. What is the most fertile ground from a pathology perspective for near death experiences, for instance? Cardiac arrest are cardiologists those most likely to hear reports of NDEs. And then The secondary question is

34:14 Does the manner of death influence the nature of the NDE reported. Let me take the second one first, guess these one to answer. The matter of death by and large does not affect whether you're going to have a near death experience or what kind you're going to have.

34:29 Now there are some exceptions to that. For example, if you are intoxicated at the time. you're less likely to have an experience. And if you do have one, it's gonna be Fuzzier and harder to remember.

34:40 Most of the research has been done with cardiac arrest patients. And That's done because number one. You got a large population of people who We can document we're close to death.

34:51 Number two. Many of those people Have no Or very few. complicating physiological problems with them.

34:59 If you study people who were on dialysis. they got many other problems going on that can complicate what's going on in the brain. But there were a lot of people who have a sudden cardiac arrest who are otherwise fairly healthy. So they're kind of a clean population to work with. So for that reason

35:13 Most of the research has been done with cardiac risk patients. But the vast majority of people who spontaneously come to me and say, Let me tell you about my experience. Did not have Cardiagarus. I say maybe

35:25 twenty or thirty percent have had a cardiac arrest, a hard stop. A lot of them are accidents. Or injuries or so forth. We have a large collection of people who were injured in combat who have near death experiences. People who fell from great heights.

35:39 This sort of thing. You blew drowned. Yeah. Just a quick thanks to one of our sponsors and we'll be right back to the show. This episode is brought to you by Wealthfront. There is a lot happening in the US and global economies right now. A lot.

So why wait? Visit Wealthfront.com slash Tim to get started. That's wealthfront.com slash Tim This was a paid endorsement by Wealthfront. Has the

36:56 Nature of reported. N D E's changed over Time. Or does it vary widely across cultures? And the reason I ask is that for instance if The

37:10 Observation of the placebo effect and how it manifests has changed quite a lot over time. There's actually a great piece in Wired magazine about this. Depending on Culture depending on how widespread readings and reporting about the placebo effect is in terms of strengthening or decreasing the strength of placebo effect. And you see examples of this also in reports of say

37:35 In some cases alien abduction or UFO encounters, et cetera. And there's sort of a homogenizing of the experience or reporting of it in some cases. That one could attribute to Mass media coverage, discussions on podcasts and so on.

37:50 So how does that apply or not apply to reports of NDs? In terms of Knowledge about new death experience, whether or a fix What are you going to say? We've done some research looking at

38:03 People who reported their near death experiences to us. Before Raymond Moody published his book. in nineteen seventy five. When nobody knew what these things were.

38:12 Working at the University of Virginia. I had access to the files of Ian Stevenson, who'd been there for many, many years, collecting unusual phenomena. And he had Maybe fifty of these cases. They weren't called new death experiences.

38:24 Some we're called deathbed visions. Some were called out of body experiences. Some recalled. Apparitions. When you look at them, they were just like the near death experiences we call today.

38:34 So I collected Twenty of those. That we had enough information about. And then match them on age, sex Beligious belief, so forth.

38:43 With twenty. We shouldn't cases that I studied. We compare what phenomena they report and what things they didn't. What we found is that

38:51 Before Moody told us what an interest experience was like. When no one had heard of these things. People reported the same things they report now. So Knowing about a knee-teh experience.

39:01 Does not affect. Whether you're going to have one or report it. Now you also asked about culture and that's an interesting point. Because most near death experiences start by saying Well there's aren't any words to describe it. There aren't any words in this I can't tell you about.

39:16 I say, You're great, tell me about it. They use metaphors. I'll say well then No, I saw this God like figure. I'm saying God'cause I don't know what else to call it, but it's not the guy was taught about in church. It was much different from that.

39:27 But this All loving, all knowing. Entity, whatever it was. And what you hear from people in different cultures

39:36 Cultural or religious Metaphors they have available to them. For example, people in Christian cultures They'll say that they may

39:45 May have seen the seeing God or Jesus. People from Hindu and Buddhist countries don't use those words. They may say they met a a Yangud, a messenger from Rama. Well they may say that I just saw this white light. Also the tunnel, you know, we have tunnels in the US.

40:01 So When people say I went to this long, dark, enclosed space. It will say tunnel. Well people of third world countries don't use that word.

40:10 They would talk about going into a well We're into a cave. I interviewed one fellow who here was a truck driver. Who said? Then it got sucked into this long tailpipe.

40:20 Ha ha. So whatever metaphor comes readily to them is what they use to describe the phenomenon. If you look at the actual phenomena they're reporting It's the same. All around the world.

40:30 And in fact, we can find cases from back in ancient Egypt and Rome. And Greece. That have the same phenomena we talk about today. But the metaphors they use to describe them. are different from culture to culture.

40:42 When you're sitting at say dinner Or you meet a Scientist outside of your field of study. who's well intentioned, they're not coming at you in some type of malicious or cynical way. They're genuinely curious.

40:58 I think. really good scientists are open minded, but they also ask for What are some of the If you had to steal man against a non materialist explanation for NDEs. Are there any

41:18 If you had to pick them. Compelling. ways to interrogate this experience from a materialist perspective. I myself as a sceptic.

41:27 Yeah, I tend to doubt everything I think as well as everything else that you think. I'm not happy of Evidence we have for some of these things. I'm still looking for it. I went into this thinking there's gonna be a simple physiological explanation.

41:38 We haven't found it. It's been fifty years and we haven't found any explanation yet. That doesn't mean we won't. So we're still looking. We have some technologies now that can

41:48 Study the brain in ways we didn't have before. Yeah, very sophisticated neural imaging. But we have much better Computer algorithms for analyzing EEGs. And we have a wider range of psychedelic drugs to use to try to s replicate.

42:02 Much of the experience in some ways. So there's a lot going on in in physiological research now. That Was not available fifty years ago. And we may some day have

42:13 A physiological answer to explain near death experiences. But let me Give you two questions. One is that If you find

42:21 always correlated with the NH experience. Brain. wave activity or a chemical That doesn't mean it's causing the experience.

42:31 Example right now. People are listening to us. And there's electrical activity. in parts of their brain that process Hearing.

42:39 It always happens. When they're hearing us this part of the brain always lights up. That doesn't mean that electrical activity is causing Our voices. It's just a reflection of it.

42:49 So when you find these physiological concomitants of a near death experience You're finding perhaps the mechanism for it. But not the cause of it. The second question though I'm a sceptic, and part of me still wishes we could find a physiological explanation.

43:04 I'm still looking. Need to remember that This is what Has been called. Uh promisory materialism.

43:12 We don't know the answer yet. But we will some day. That's a perfectly fine philosophical position. It is not a scientific position. Because it can never be disproven.

43:21 You can always say, Well, we haven't got it yet, but we'll get it in fifty years. So you can never disprove it. So it's not scientific. So saying that that's a scientific way of dealing with things, promisory materialism is not the way to go. We need to deal with what we have right now and how we interpret what we have right now. I think

43:37 Most people who study engage experiences, whether they're spiritualists or materialists. or neurophysiologists or philosophers. The Greece of the Phenomenal. They don't agree on the interpretation of it.

43:50 Of what's causing it and what its ultimate meaning is. I think that's fine. That's not where I am. I'm not a philosopher. I'm not interested in the in the ultimate cause or the meaning of it. I'm actually

44:02 A clinician. So what interests me most about near death experiences is how they affect people's lives. And what people do with the experience. And that's the same regardless of what's causing it.

44:14 Whether it's a hallucination or a spiritual experience. It affects people in the same way. And that's I think What interests me most. So uh we'll probably come back to this, but I'll just

44:25 Maybe as a uh It's a teaser for folks. And please fact check me if I get any of this wrong, but it seems like some of the common after effects. for those experience N D E's are increased altruism, a feeling of connectedness if they

44:41 had a profession involving some degree of violence, for instance. Not necessarily ill intentioned, but law enforcement. If they were in the mafia, I know there's a case of this. Yeah. they're no longer capable or willing to perform those jobs. Right. those who have attempted suicide and have the experience of an NDA counterintuitively are less suicidal.

45:04 After the fact. So I'll Provide those as teasers. But just to scratch my own itch. I'm gonna pick up on a thread from Quite a few minutes ago.

45:14 Where I was Asking about Possible differences in reported NDEs. Do children and adults report the same phenomena, obviously using different metaphor. Yeah. For trying to convey the ineffable, perhaps. Do they differ in any notable way?

45:35 The one difference is that children don't have the elaborate life review that Most adults do. Yeah, it's much of a short form. deceased relatives that they might encounter. They have some.

45:49 But you're more likely to hear from children. Encountering a deceased pet, a dog or a cat. But by and large people have studied. Children's near death experiences. Find the same phenomena.

46:00 They often even more than adults do in putting it into words. So they will often ask the children to to draw what happened. And they produce artwork to explain the death experience.

46:11 You're mentioning new tooling, new equipment. And technological capabilities that we have, whether that be F M R I or some type of advanced Brain imaging. The use of

46:24 Computers, algorithms, certainly AI at some point, if not already, to analyze EEG, E G G data, and so on. How might you use something like brain imaging if you could design a study because presumably if someone's about to flatline you're not going to slide them into an FMRI machine because you would the clinicians would not be able to get to them. So would that mean you would be putting someone into say an an FMRI And then doing your best to simulate.

46:56 An N D E with exogenous compounds such as psychedelics or otherwise, how might you use the brain imaging? Brain imaging with psychedelic drugs. We used to think that

47:09 Psychodellas work by stimulating the brain to hallucinate. And what these studies have shown. Is that the Sagadilla trips that are associated with more elaborate Mystical experiences.

47:21 are associated with less brain activity. And less coordination among different parts of the brain. sort of getting pushed out of the way by these drugs. Allowing

47:33 Whatever it is to come in all this uh mystical experience. People have tried to look at brain function during a cardiac arrest. It is not easy.

47:43 Several papers have been published in leading neuroscience journals. Claiming they have done this. But they have not done that. For example, once that it was published of the People who were

47:53 Comatose. And on life support. They said it was happening in the brain. When they stopped the artificial ventilation. And what they found was that there was

48:03 A change in the brain function. When they did that. It was reported as an increase in gamma activity. It was actually not. All the brain waves were decreased. When they stop the ventilation.

48:15 But the gamma waves were decreased less than the alpha beta and delta. So it looked like there was more Relatively speaking. Of the gamma. It was actually less than it was before.

48:25 But these people were not Dead. They also reported Heart function during this time. And when they were reporting these.

48:32 Changes in brain waves. The people's hearts were still beating. They were still having a a normal sinus with a normal normal heartbeat. When the heart did stop. they didn't continue doing the EEG, so you couldn't continue to see what's going on in the brain after they actually died.

48:47 But they report it as Electromagnetic activity in the brain. in dying patients. Well they weren't dying. They'll just The artificial respiration was stopped, but their hearts were still beating.

48:58 Similarly, there were other studies like this. Were they claim to be reporting on dying patients, they really were not dying patients. They were people who were approaching death. There was a study done in Michigan. Where they sacrificed

49:10 Res. And measured what's going on in the brains when they do that. And they reported a thirty second burst of activity. After their heart stopped. That's what they said they found.

49:21 Actually wasn't a burst. If you look at the traces they give you It was a A slight increase. But far less than the brains were showing before they sacrificed them.

49:32 So it was a tiny blip, it wasn't a surge. Like they said it was. Furthermore If they anesthetized the rats. They didn't show this at all.

49:40 Obviously people have N D E's near death experiences under deep anesthesia. So that's not the same phenomena. There were several other things that weren't Untypical of near death experiences, for example. Every single one of the rats they tested.

49:53 had this burst of activity. But if you ask people who come close to death, only about ten or twenty percent have near death experiences. And probably most significant. They didn't bother to interview the rats to see what they were experiencing. Yeah.

50:07 I will mention one researcher who has actually measured E G's brain waves. During cardiac arrest. And this is Sam Party uh NYU. But when you're resuscitating somebody.

50:19 You Press on the heart, you compress the heart, heart compressions. for a while and then you stop and give'em a break to see whether the Spontaneously, breathe or not. And then you continue it again.

50:30 Or there Shocking them with with electricity. And then you stop and see what's happened. And he measured the brain waves. During that period when they stopped.

50:38 Thinking this is gonna tell us. What's going on? Well I'm not sure it is because It's only for a few seconds that you're stopping. And the body is still suffering from the shock of the electricity.

50:48 Or the chest compressions. Furthermore, he reported some Increase in several different With things of of brain activity. In about half the patients.

50:58 He also reported that there were some six patients. Who we put in new death experiences. They said, Well obviously the The increased brain activity is causing the near tooth experience. If you look at his data.

51:09 The six who had the near death experiences did not have the increase in brainwaves. And those who had the knee death increasing brainwaves did not report near death experiences. So I'm not sure if it if we learn anything from that. Alright.

51:25 Ask you to make some sort of theoretical leaps to answer the next few questions. But first Because I have to ask this. When people see Or claim to have seen.

51:37 Deceased relatives. How and I don't know if you have this level of Granularity in the reports. How old? Are those deceased relatives? Are they

51:47 last they saw them because presumably some of these people who died would have had a slow decline. Right. Neurodegenerative disease and so on. So do they appear much younger? Is there any Pattern. in the reports whatsoever in terms of the age.

52:03 That these people seem to be When they are. Observed. There was a pattern, but again. I need to fall back on the fact that

52:10 Most people say there aren't any words to describe it. So when you ask them to describe what they saw. You're describing what the brain interpreted of what they saw. And most people say that They saw the deceased loved one.

52:23 At the prime with their lives. When they were young and healthy. Not. When they were dying. I have had some people say

52:30 Annually see a f a human figure. I just saw my grandmother. Well, how did you know it was your grandmother? I felt her vibrations, I knew it was her. It was at her essence. So they may have just seen this blob of light.

52:42 And knew by the way it fell to them. This is grandma. There's no way of validating this type of thing. It's just their impression. Alright, let me ask a sort of tactical practical question and then we'll get into this the stranger stuff. Sure.

52:55 If you had let's say there's someone listening. And they're like, Okay. I'm not sure I want my name on it, but as an anonymous donor. I'm willing to give. Doctor Grayson. Some sum of money.

53:07 Or maybe some secret agent at the NIH is like you know what? I know it'll liberate some funds. Right. What studies would you like to Design and see done. I mean they don't need to be specifically related to N D E's, but If they are, I suppose that'd be more tremendous the conversation.

53:24 Any types of studies that you would Love to see. Performed related to this? I can answer that from my personal perspective, which is not What I like to see the field do.

53:35 Sure. I'd like to see the field do is what they're doing right now. looking at all the different possibilities. looking at cross cultural comparisons. Look at neurophysiological changes.

53:45 The types of things now. Other phenomena that Seem to mimic parts of the NDE like psychedelic drugs. But that's not where I am right now. I'm nearing the end of my career.

53:55 And I'm falling back on What does it all mean? And For me, what that means is How does it affect people's lives?

54:05 So I would like to see more research. Into The practical applications of new death experiences. We've done some studies now with

54:14 Near death experiences would say they needed Help. We adjusting to a quote normal life. After a needed experience. And we've surtained them about

54:24 What did they need help with? What was so disturbing about the experience or its after effects? What type of help did you seek? What type of health did you receive? What type of practitioner did you go to?

54:36 Psychiatrist. A doctor. Yeah, spiritual hook healer. A pastoral counselor? And what types of help were actually helpful and which ones were not helpful.

54:45 And we're finding some interesting findings from that. We're also surveying Physicians. About their attitudes towards near death experiences. And we post on the question, if a patient comes to you and says

54:56 I had this experience that I want to tell you about. Would you feel comfortable? Talk with them about it. And what are the barriers you feel? Two

55:04 Open up and talking about them. And we had a list of some twenty five Possible barriers we thought might be. Things they said. And we were very pleased to find that almost none of them said

55:15 I don't think it's worth talking about. It's not important. Or It's just a Neurological artifact. Does it mean anything? Or just type of psychosis.

55:25 By far the most common Response doctors gave was The barrier is I don't know enough about the experience to talk to patients about it. And the second most common was I don't have time to talk about this with my patients.

55:38 I'm just too busy. Those are both things that we can correct. We can certainly give more training to physicians. And we can restructure the schedule so they do have time. To talk to patients.

55:48 What are the most if any reliable ways to simulate an N D E or N D E like experience. And it makes me think back to a movie it may not age well, but I enjoyed it at the time with Keefer Sutherland. Two thousand no, it was prior to that, 1990 something called Flatliners. Right. There are medical students who would take turns putting themselves.

56:12 Right. Brief of death. And then they get into this arms race of competing with one another and pushing it further and further and further. But My understanding based on Some of what I've read, you do have familiarity with some of the psychedelic related science is that These NDEs seem to produce more What have been described as out of body experiences.

56:36 perhaps more I don't want to say reliably, but more frequently. than psychedelic experiences, but are there any we'll come back to that point. But are there any ways to simulate it in such a way to make it more Studiable. even if it's not the exact phenomenon, since I'm sure the IRB would have a tough time accepting temporarily killing patients or uh subjects that are recruit for a study.

56:59 Is there anything that approximates it or any thoughts on how we might do that? Keeping in mind, and this is an imperfect example, but long ago, decades ago, psychedelics were viewed as psychodometics. So they can be used as a tool for effectively eliciting a psychotic episode so it could be better studied. Now That ends up not being. Quite right. But how would you think about

57:24 Approximating. N N D. I don't think there's a good way. I think The tool we have that comes closest are certain psychedelic drugs. In a very

57:34 Supportive environment. I don't think people just taking drugs on their own. can necessarily replicate a new death experience. But in a supportive environment in the lab. With the low lighting and and good music and someone there to help you with it.

57:47 You can replicate some of the features. of a new death experience. Not all of them. And you tend not to have a All the after effects.

57:56 And I think that's understandable because if you have an experience under drugs, you can say, Oh, that's just a drugs, it wasn't real. Whereas if it happens spontaneously is hard to dismiss. One of the issues with the drugs Is that we And find out what's going on in the brain.

58:11 When people are given these drugs. And that's fine. But then you make the leak to saying Change in the brain that occurs during a depth of experience.

58:20 That's an assumption. We don't have the evidence for that yet. It tells us. How he might look. For places in the brain. Where we might look and what types of changes.

58:30 But that work hasn't been done yet. So it's all speculative. Certainly. The drug induced experiences. are not identical to near death experiences.

58:39 Many Nate experiencers have tried drugs. Afterwards to try to replicate the experience. And the university tell me it's not the same thing. Oh one person told me When I was on psilocybin.

58:52 I saw heaven. Was in my near death experience, I was in heaven. That was the way he explained it. But they tend not to have the same after effects. And one question of that I w say is that

59:02 The recent work done at Johns Hopkins with psilocybin. Has found A marked decrease in fear of death. After

59:10 Oh short. Experience with solocy. And they don't follow up in this at least a year after the experience, they still have that decreased fear of death and it's very encouraging. Yeah, it's surprisingly durable. Uh directly correlated with the

59:23 strength of the mystical experience which is measured using an assessment much like your scale for N D E is. Yeah. What other characteristics?

59:37 Seem to be a little bit more. hard to replicate with drugs or Less frequent in occurrence. And perhaps this is an opportunity to speak to what exactly an out of body experience is, as you would define it. And I think we already gave perhaps an example of this with the wings flapping.

59:57 But Can you say more about that? It's tricky to define an out of body experience. There's a large body of evidence. Looking at

1:00:06 People who have their Temporal lobe of their brains stimulate electrically. And There were claim they produce out of body experiences. They do not. They may produce a sense of

1:00:15 Nothing aware of your body anymore. But they don't produce a sense of Leaving your body and being able to turn around and look at your body and seeing it from an out of body perspective. They often say That with the stimulation

1:00:26 You can see a double of yourself. But you're seeing it from inside the body, you're not outside the body. And The W C is static, it's not moving around. Whereas people who have real out of body experiences talk about

1:00:38 Moving around the room. Well get distant places. People who have out of body experiences. Sometimes

1:00:45 things accurately that can be corroborated later on. That doesn't happen with stimulation of the temporal lobe. So there are a lot of differences between these Artifacts.

1:00:54 That are produced by the Temporal stimulation. and real out of body experiences. When you read some of the papers that have been published about temporal lobe stimulation.

1:01:04 They say things like Well My legs were getting shorter. I felt like I was falling off the Granny. And they're called these.

1:01:11 out of body experiences, they're not. Their somatic hallucinations. But they're not out of body experiences. You can get out of body experiences with other types of mystical experience and with psychedelic drugs.

1:01:24 Well the same. or not is kind of open to question right now. We don't have examples of people having uh drug induced out of body experiences. having accurate perceptions of what's going on.

1:01:36 Around them. As you do with near death experiences. Yeah that may be'cause we haven't looked. Deep enough, yeah. We may find them.

1:01:44 At this point, we don't have that. Sure. A strange experience and then we'll get into the as promised to the listeners, this the some of the stranger stuff. But not that this is just a plain vanilla walk through the The DSM. So I have a fair amount of flight time with different psychedelic compounds and the

1:02:05 One Time. I would say I consistently experienced what you would describe or might describe as an out of body experience. was in using and I

1:02:16 highly discourage anyone to use this. A turpenoid. called Salvinorin A, which is found in Salvia Divinorum. otherwise known as diviner's sage used by the Mazatecs in Mexico for centuries, probably millennia. And

1:02:30 Part of the reason I don't recommend it. Well, first of all, you could go on YouTube and just search Salvia freak out, and you'll get lots of video footage for why you should probably steer clear of it, but it's a as I recall, a kappa opioid agonist, and that is Consuming an agonist. of the kappa opioid receptors typically is described as acutely dysphoric. So what is dysphoria? Well it's the opposite of euphoria. It's horrible. Terrible, terrifying experience for most people. So I don't recommend using it, but

1:03:01 These experiences are notable for two reasons. Number one, I had no expectancy. No I didn't know anyone who had consumed. A purified. Savan or Nay. And

1:03:13 Secondly, I was observed by clinicians and in one case was inside an FMRI machine, so I could not see anything outside of the Machine. But in both cases the experience was effectively a flattened Abstract experience.

1:03:30 Devoid of time, space, a sense of self. None the less there was an observer, but incredibly bizarre. experience even compared to say a Cell7 or an N DMT or something else. And in each instance, I had two experiences at some point mid Abstraction.

1:03:48 I effectively f had the view of a C C T V camera in the upper corner of each room. And I was able to see what all the scientists were doing, all the clinics. And was able to corroborate those after the fact. Now, in the first instance, I was not in an FMRI machine, so people might say, Well, you could have had one eye open and you could have been watching. No I I would challenge anyone in the depth of this experience to attempt to report anything visual with their eyes open. But

1:04:17 The Fact that I was Literally. strapped down inside an FMRI machine would preclude any Ability.

1:04:26 as we currently understand it, to use my eyes to see anything. And that raises some questions for me, because I do have a reasonably broad palette of experience with different molecules. But That was two for two, and I haven't experienced that in anything else.

1:04:43 This is slowly meandering into the stranger territory. So it seems to be the case that certainly we can occasion very strange experiences. with the ingestion or inhalation of different compounds, right? So the brain has some role as a mediator of experience in the world. But then you seem to

1:05:08 document in your experience. These phenomena that seem to reflect a Mind beyond brain. for lack of a better descriptor and I don't want to put words in your mouth.

1:05:22 How do you begin to even think about this? And Is the brain I suppose we could make an argument for this. on a whole lot of levels, eh? reducing valve, as Alvis Huxley might put it.

1:05:34 Right, that is filtering for Information that is optimized for survival and procreation. And when you Do something that

1:05:48 I suppose opens the aperture of that reducing valve, then suddenly you have these experiences. Is the brain acting like a Reiver of some type. Now the argument against that would be well If you damage the brain.

1:06:02 you can observe all of these effects on perception and cognition and so on. How at this point, given all of your documentation Discussions with colleagues in and outside of this area of expertise. Think about it Mind versus brain. With the understanding that there's A lot more we don't know than what we know.

1:06:22 Right. But how do you think about this? I was taught in college and medical school that the mind is what the brain does. And all our thoughts and feelings and perceptions are all created by the brain. And I cannot believe that anymore. Seeing people who whose grains were either offline or severely impaired.

1:06:40 Telling me they had the most elaborate experience they've ever had. So I'm inclined to think that The mind is something else. And the brain kind of filter it, as you said. This is not a new idea.

1:06:51 Two thousand years ago, Hippocrates said this that The brain is a messenger of the mind. This is not surprising because we know That the brain has these filters. There's the default boat network in the thaumaloctical.

1:07:03 Network. If people are listening to us now. They don't really care what we look like. They want to hear what we're saying. So they're Thalmacortical circuit.

1:07:13 Taps down. The visual input. And focuses on the auditory input. And likewise we're not hearing the train go by outside or the the traffic outside'cause we're focusing on this. And that's your brain doing that.

1:07:25 It's filtering out. What stimuli you gotta pay attention to? And it starts even beyond the brain at our sense organs. Yeah, you don't see all the visual Light that's out there.

1:07:34 You just see the small portion that is in our Visual spectrum. We don't see infrared and ultraviolet. And likewise we only hear A small fraction.

1:07:42 Of the frequencies of sound available. We don't hear the sounds that the dogs and bats hear. Or elephants and dolphins. So our brain And the associated sensory systems that we have with that.

1:07:54 Filters out things that are not important to our survival. And we think about the things that happen in near death experience. Seeing deceased loved ones. Leaving the body. That's not essential for survival.

1:08:04 You can get food and shelter in a mate and avoid predators without all that. So it makes sense that the brain would normally filter that stuff out. And not pay attention to it. And if in a near death experience Or similar experiences.

1:08:17 The brain is shutting down selectively so that that filtering mechanism is Put on hold. Or being weakened. Then you have access to this other consciousness.

1:08:27 Now it raises the question of what is this other consciousness, where is it? In a way, that's uh A bogus question because If it's A non physical entity, how can I have a where? We can't be any place.

1:08:38 But I'm not a philosopher. I'm an empiricist. And when see people say to me. As many do.

1:08:45 If you have this non physical mind How does it interact with the physical brain? I have no idea. On the other hand If you take a materialistic perspective and say

1:08:56 How does the brain The chemical and electrical changes in the brain. Create. An abstract thought. We have no idea about that either.

1:09:06 So Whether you're an empiricist U materialist or not. We can't explain how thoughts arise. And how they get processed to us.

1:09:15 But we do know. Is that all our experiences are filtered to us. Through the brain. You can have the most elaborate mystical experience in the world. But to tell me about it.

1:09:24 You have your back in your body. With words created by your brain. And filter through concepts that your brain puts on it. So Obviously the brain is evolved.

1:09:34 In Perceiving. And processing and relating the near death experience. You can't get around that.

1:09:40 Doesn't mean it's creating it. And also I just wanted to add, and I've heard you discuss this, just because something is currently unexplainable does not mean it is fundamentally unexplainable. But if we look back at the history of science. And uh certainly

1:09:56 This will continue to be the case. We would laugh at some of the presuppositions of two hundred years ago. And There's no reason to think that A hundred, two hundred years from now. Certainly with the rate of technological change maybe five, ten years from now.

1:10:10 Almost with certainty. We will look back at many of the Things we took to be true. Now and laugh at them. Similar and that in science everything is provisional in a sense. Right, it is until proven otherwise, which it almost inevitably is.

1:10:27 Something that's added to it. It would seem to me that Study this field documenting these cases doing your best to make sense Of these things.

1:10:40 Is not without career cost. It would seem to me, and certainly this was the case with psychedelics, say a few decades ago. Yes, to to try to scientifically study psychedelics, putting aside all of the nightmares of logistics with dealing with the FDA and handling schedule one compounds and so on. to take that path was views as career suicide.

1:11:03 And I don't know if that's a fair label to apply to your field of study with respect to N D E is but What have the cost been, if any?

1:11:15 And why have you persisted Despite those costs. is less of a problem now than it was back in the nineteen eighties. When No one knew about these things.

1:11:27 Most academic centers assume this was just A few crazy patients telling us stories. And they were worth. Investigating. And I was told in one university

1:11:37 That if I continue to study these things. I would not get tenure. So I've ended up leaving that place and go to a different university. before they came up for tenure, I wasn't willing to risk that. But I did now get tenure at two subsequent universities where it's become more acceptable to study.

1:11:53 Unusual phenomena. As long as you're doing it in a scientifically respectable way. And publishing your material in Mainstream medical journals. So I think it's less of an issue now, but you still see A lot of

1:12:04 I wouldn't say it's it's Professional suicide. But certainly. Provisional barriers. being raised to people who study these things.

1:12:12 I think Why people do it? Partly because they're intellectually curious about it. There's a challenge here. I don't understand it, and I want to. And probably more importantly for me is These experiences have profound effects on the people who have them.

1:12:27 This is a psychiatrist. I want to understand that. And help them deal with those effects if they need help with it. I think it's irresponsible to is just to ignore it and say it doesn't exist.

1:12:37 Let's talk about some of your other Interests, research interests. And I have A note here, genomic study of extraordinary twin communication. Could you elaborate on this? This actually was not my project originally. The Israeli psychologist Borg Fishman

1:12:53 Contacted me and said. I've got this great study I'd like to do. And I found a twin genomic database in England. They've got fifteen thousand pairs of twins and they the entire genomic

1:13:04 platform all laid out. So we can Survey these twins they have. But what they've had. Some type of communication when they're at distant locations, what you call telepathy, you can call

1:13:15 Extra sensory. You can call it coincidental. But they have reliable communication with each other when they're far away from each other. Can we find out from the genomic analysis? What genes are associated with disability?

1:13:27 I thought. That sounds interesting. One was something I would pick, but Sure, I'm I'm getting to try that. So we did apply for a grant.

1:13:35 And we got the approval of the group in England. But the study hasn't actually started yet. But it makes me wonder about The genetics that goes into having a new death experience.

1:13:44 Yeah, we've been studying What's going on in the brain? What's going on in the heart and lungs. We haven't scratched the surface of what's going on in your genes. That they make you

1:13:54 more likely to have any death experience or a certain type of experience. Now we know that When their hearts stop. Between ten and twenty percent of people will have a near death experience. We haven't found any way of predicting who's gonna have one or not.

1:14:07 But maybe the answer is in the genes. So I think it's worth doing a genetic study of people who have NHEF experiences and those who don't. I've had uh A handful of Guests on this show.

1:14:18 You have to have Identical twins. And They have all Maybe off the record. I think in some cases on the record in conversation.

1:14:29 shared with me stories that certainly defy any current conventional explanation of communication with their twins. And It's a hundred percent. at this point. And I've only had a handful of Individuals with Identical twins, but

1:14:44 In several cases, these are scientists, these are People who are otherwise as kind of rational materialists as you could be but they are not going to refute their own direct experience, continued direct experience with their identical twin. Does raise a lot of questions. And if we want to get really sci-fi, you think about Genetic engineering, you think of CRISPR, you think of gene therapies. If we were to in some

1:15:09 capacity determine which code is responsible, which light switches are responsible. Would it be possible to increase someone's ability to express those capabilities in the same way that we might say Toy with myostatin inhibition or something like that.

1:15:26 Two Analize increased. Muscle growth in the In the sense you might see in bully whippets or in Belgian blue cattle as an example. Certainly seems like a study worth doing. Why not?

1:15:39 I mean, worst case you find no correlation. There's a lot of ifs in that question. Yeah, if we could do this, if we could do that. Lots of ifs. Lots of ifs. Yeah. Frankly, I'm not encouraged by what I've seen so far with genetic engineering. We we can make Tomatoes.

1:15:53 With a thick skin that can travel better across country. But they don't have the flavor that normal tomato does. So you're always paying a price when you genetically modify something. You may gain something you're looking for. That you may lose something else.

1:16:07 When you start messing with human genes You don't know what you're gonna come up with. Oh, for sure. How much funding are you seeking for this particular twin communication study, the genomics.

1:16:17 Study. That's a small one, just fifty thousand dollars or so. In the realm of science, that is. Very inexpensive.

1:16:26 outside of N D E is would you like to See Don, are there any that are kinda shovel ready, so to speak? Or close to shovel ready. We've mentioned people who claim to leave their bodies and see things accurately from an antibiotic perspective. I will have to get

1:16:40 A more controlled version of that. And people have tried that. Sampornia NYU has tried it a couple of times. I didn't turn it for it once. There have been total of six published studies of attempts to do this.

1:16:52 And none of them have been successful. Usually you'll study things for a year or two and find no need experiences in your sample. Or people who have an N D E but Didn't describe. Seeing things from an out of body perspective. So there really hasn't been any tests with this yet.

1:17:06 Determined skeptic could say, Well that Shows that It doesn't really happen. the people who spontaneously have this experience and tell you about it. are misinterpreting what's happening to them or just making it up.

1:17:17 And I would desperately like to find some objective way of measuring this, but we haven't had that yet. So it would be nice to Turn it. And then try to find A good way.

1:17:26 Of studying this in a mess. The Soth Sam Partners I was participated in one of his studies. That had two thousand patients in it from a variety of hospitals. And we found nothing in that room.

1:17:38 So you need a huge study to do this. This was related to out of body experiences. Specifically. Mm-hmm. Yeah.

1:17:45 Yeah, I I think there's a lot to be learned from The neurophysiological research that's going on now. There's a very active group at the University of Liage in Belgium that's making headway with this. There were other people around the world who were studying it. It was a group at University College in London.

1:17:59 But I think we're a long way from having an answer yet. We're just starting this type of research. And it may be certainly not in my lifetime before we find a good answer. Is there a Study. That you think

1:18:13 Would be a More Intelligent way. Or a better way to approach. Controlled study.

1:18:22 or assessment of out of body experiences. And part of the reason I ask is that If you look back At for instance. Could give a famous example. The amazing Randy.

1:18:33 Who had this Outstanding. Prize, I think it was a million dollars or a hundred thousand dollars for anyone who could demonstrate psy abilities or extra sensory perception or fill in the blank under controlled conditions. And to my knowledge, no one ever claimed that prize.

1:18:50 No. At the same time, if you look at a documentary like For instance, I believe it's called Project Nim. Which Looked at the

1:18:59 In retrospect, ill-advised idea to try to raise a chimpanzee as you would a human child. The chimpanzee demonstrated all sorts of learning behaviors. And So on that could not be replicated in the lab.

1:19:13 simply because the chimpense would shut down would not demonstrate those behaviors in a laboratory setting. That doesn't mean they didn't exist. But There are challenges in studying it in a controlled environment.

1:19:27 What is your best Explanation. Again, understanding that for a lot of people, if you can't verify it under double blind placebo controlled conditions or the equivalent in this setting, then it doesn't exist with extreme claims.

1:19:41 comes the requirement of extreme levels of proof. Look. How would you Based on everything that you've studied colleagues you've spoken with, explain why it is so difficult to

1:19:55 produce or replicate or study these things in controlled settings. Why is that? It's essentially Spontaneous experience. That does not happen under control conditions. When you put someone in a lab

1:20:06 They're not the same as they were when they're out on the street. We've learned this with sleep studies. When you bring someone To measure their brainwaves during sleep.

1:20:16 It takes you a day or two usually to have them adapt to the situation before you can actually do it. You get something that's at least a bit like What their normal sleep is. So I think you have to take that into account that people have these experiences. Out of the wild, so to speak.

1:20:29 And it's hard to tame it without clamping down on the controls to their brain that would shut it off, maybe. So I don't know whether you can do that. Well you can have a really controlled circumstance. We have this experience.

1:20:40 You can certainly do it with mimics that mimic part of the experience, for example with drugs. Or with brain stimulation. That can mimic a part of it. And then

1:20:50 By implication. Develop metaphors what might be going on in the brain during a death experience. It's not the experience itself. What are some of the For you personally.

1:21:01 open questions that you would love to See answered. before it lights out onto the next adventure after death. If there is a next adventure. What are some of the open questions in this field? Or in other fields that for you you would most like to

1:21:21 See answered. Are there any burning questions that come to mind? Well, the big question of course is how their mind and reign indirect. And That's certainly You get some hints of that from a near death experience.

1:21:34 But there are other phenomena that also address The mind and brain seeming to to separate. And one of these is the terminal lucidity phenomenon, where people who have had dementia for a while And can not communicate Or recognize family.

1:21:49 suddenly become completely lucid again. And carry on coherent conversations. And express appropriate emotions. And then they die. Usually within minutes or hours.

1:22:00 And we don't have any explanation for this. I have a few friends, not just one, few friends who've directly seen Observe this phenomenon. And I do not have any way to explain that.

1:22:10 If you believe the brain as filter mechanism. That could play a role in this. When the rain is shutting down. In the last hours before death. It releases this filter.

1:22:22 That allows you. the consciousness to to fully flourish. No. A big problem with that is The person is still able to speak and communicate.

1:22:32 So obviously parts of the brain are still functioning just fine. So if you have this experience of high lucidity at death How do you Let people know that unless your brain is still functioning. It is a dilemma.

1:22:44 Because We don't have any medical explanation. For have someone with a debilitating disease that is irreversible, like Alzheimer's disease. can suddenly regain function again.

1:22:54 There are speculative theories about this. But none of them really make a whole lot of sense and none of them have been Corroborated by by evidence. Now there are other facets of some of the report in N D's past life review. As an example.

1:23:07 you might also have, as I understand from listening to uh a number of your presentations recall or re-experiencing an event through the perspective of someone other than yourself. When you consider all of these reports. How is that affected, if at all, how you think about time? And

1:23:30 I ask that it might seem I think most of us tend to think of time as this fundamental constant, but if you talk to You know, the Carlo Rovelli's of the world, if I'm pronouncing his name correctly, if you start really digging under the hood It's difficult to automatically take that as

1:23:50 Sort of static. No one. Fact. And I'm wondering how you think about Time.

1:23:57 If these reports and your research and experiences have Change that at all. Most near death experiences say there was no time. In this other realm. Either that.

1:24:09 Time stopped. Or just time cease to exist. And when they say that I reflect on what they've told me about the experience, I say, Well But you're telling me that

1:24:19 This happened. And then this happened, and then this happened. That applies. Linear time. So how can there be no time if you've got things happening in sequence?

1:24:28 And they just truck and say, Well Well I tell you about it now. In this body in this world. It's a paradox. Over there it wasn't.

1:24:37 Everything was happening all at once and there wasn't any linear flow. That's just the way it is. I can understand that as an abstract concept. I can't relate to it in my real life. I don't know what that means.

1:24:48 To not have time. But so much of our life is controlled by What we think of as the linear passage of time. It's a slippery one this time thing. Wh when you have some of these uh non ordinary experiences. Let me ask about another

1:25:02 Perhaps non ordinary experience and this is something I found in the footnotes of a footnote of a footnote. It's so Yeah. You may have some ability to explain this. Auditory hallucinations after NDs. I only read the very top abstract in a PDF, so I did not dig into it, but

1:25:21 What does this refer to? A psychiatrist in Colorado, Mitch Leister and I did this study. Uh we surveyed a large sample of near death experiences about what seemed to be hearing voices. Long after the knee death experience. And we also looked at

1:25:35 Schizophrenics. Who are hearing voices. and compare the experience of those two groups. And they were quite different. The near death experiences who claim to still be hearing voices.

1:25:44 Almost universally. Said these were helpful. Diding voices. They enjoyed hearing them. And they found them making their lives richer.

1:25:53 They gave them some guidance. And they were kind of reassuring to them. On the other hand. The schizophrenics almost universally said. These are terrifying hallucinations.

1:26:04 I wish I didn't have them. They made my life much harder. I don't like them at all. Which they would just go away. It's not experienced in the same way.

1:26:12 Is the same phenomenon? I don't know. Among the people who reported the auditory hallucinations. Was there Any degree of overlap in terms of structural

1:26:26 Brain damage or otherwise. And the India Group. We don't have the measures of brain function to to answer that. To know. Yeah. I could keep going for many, many, many hours. Let me ask you this.

1:26:38 Just as a way of branching out a little bit. In terms of researchers who In your mind. Demonstrate. a compelling combination of both

1:26:51 Open mindedness, but Rigorous skepticism. Who would you Not to ask you to pick among favorites, but who are a few names? that come to mind.

1:27:02 Sam Parnia at NYU? How do you spell uh his last name? D A R N I A. Mm-hmm. Got it. There were

1:27:10 A retired physicians who are still involved in this field. Peter Fenneck in England. And Pim Van Lummel? In the Netherlands? There's a

1:27:20 Brilliant psychologist in New Zealand. Natasha Tassel Malamua? who's doing a lot of interesting research in this area. She has Part Lowry. And she's doing work with cross cultural

1:27:31 Comparison of Maori versus English near death experiences. Also looking a lot of the after effects. There's that large group at Liege that I mentioned to you before that's doing a lot of research into this. This is Belgium.

1:27:43 Yeah. Many of them are quite confirmed materialists, um, that's fine. They're still doing good research. The head of that lab, though, Steve Lorry's. is much more open minded. He still is materialist, but he's more open minded about what these things may mean. And he's certainly compassionate about

1:27:58 How it affects the people who have these. Which is probably more important to me than what they Think it's causing it. So there are a number of people around the world. who are doing good research with this area.

1:28:08 You have written a number of books. And co authored, co edited. Others. One of them is irreducible mind towards the psychology for the twenty first century. What does the irreducible mind Refer to.

1:28:24 Yeah. Basically means a uh A mind that's not reducible to chemical processes, electrical processes in the brain. It's a mind that can be independent. Of the brain.

1:28:34 And that book Without ever mentioning anything. Paranormal or parapsychological. Cost she was she was a phenomenon. In everyday life.

1:28:43 that point to mind and brain. Not being the same thing. And it does include near death experiences. and other experiences near death. Includes

1:28:52 Exceptional genius. Into psychosomatic phenomena. A variety of things that have occurred to Perfectly normal people. Over the centuries.

1:29:01 And they've been well documented and don't seem to be compatible with idea that the brain creates All our thoughts and feelings. Which of your books Whether solely authored, co authored, or co edited would you suggest people start with if

1:29:17 They wanted to dive deeper. I would suggest My most recent book, After Because that's really geared towards The average person, the layman.

1:29:27 As written in Language we're talking right now. I tried to minimize jargon. Whereas the other books I've written are br primarily for Academicians.

1:29:36 Which are much harder to read, much denser. Still excellent books, but not for the average person. And that is after subtitle A Doctor Explores What Near Death Experiences Reveal About Life and Beyond. Right. All right, so that's where people should start. Well, Doctor Grayson, this has been a very wide ranging conversation. Is there any

1:29:53 thing that you would like to Discuss, mention, or request you'd like to make in my audience, something you'd like to point them to, anything at all that uh you'd like to say before we start to Wine to a close? I think that Things I want people to know about near death experiences are number one.

1:30:10 That they're very common. About five percent of the general population or one every twenty people has had a dear death experience. And secondly, that they are not associated in any way with mental illness. People who are perfectly normal. Have these

1:30:24 And he ease. in abnormal situations, but can happen to anybody. And third, that they lead to sometimes Profound long lasting after effects. Both positive and negative.

1:30:35 that never seemed to go away over decades. All things Bruce Grayson, it would seem, at Bruce Grayson.com. If I'm not mistaken. So Bruce Grayson, G R E Y S O N dot coming. And you have quite a few books to your credit, but the one to start with would be after subtitle A Doctor Explores What Near Death Experiences Reveal About Life.

1:30:57 And beyond? Is there. Anything else? I think that's it. You covered it pretty well, Tim. All right. Well thank you very much for the time. And for everybody listening, we will link to everything that we discussed.

1:31:09 In the show notes as per usual at Tim Dog slash podcast and you can just search Bruce probably and he'll pop right up. And as always, until next time, be just a bit kinder than is necessary, not only to others, but to yourself. And thank you for tuning in. Hey guys, this is Tim again, just one more thing before you take off, and that is Five Bullet Friday. Would you enjoy getting a short email from me every Friday that provides a little fun before the weekend? Between one and a half and two million people subscribe to my free newsletter, my super short newsletter called Five Bullet Friday. Easy to sign up, easy to cancel.

1:31:45 It is basically a half page that I send out every Friday to share the coolest things I've found or discovered or have started exploring over that week. It's kinda like my diary of cool things. It often includes articles I'm reading, books I'm reading. albums perhaps gadgets gizmas all sorts of tech tricks and so on that get sent to me by my friends including a lot of podcast guests and these strange esoteric things end up in my field and then I test them and then I share them with you. So if that sounds fun again it's very short a little tiny bite of goodness before you head off for the weekend, something to think about. If you'd like to try it out, just go to Tim.blog slash Friday. Type that into your browser, Tim dot blog slash. Friday, drop in your email and you'll get the very next one. Thanks for listening.

1:32:34 As many of you know, for the last few years I've been sleeping on a midnight luxe mattress from today's sponsor, Helix Sleep. I also have one in the guest bedroom downstairs and feedback from friends has always been fantastic. Kind of over the top, to be honest. I mean they frequently say. It's the best night of sleep they've had in ages. What kind of mattresses, or what do you do, what's the magic juju. It's something they comment on without any prompting from me whatsoever. I also recently had a chance to test the Helix Sunset Elite in a new guest bedroom, which I sometimes sleep in, and I pick it for its very soft but supportive feel to help with some lower back pain that I've had. The Sunset Elite delivers exceptional comfort while putting the right support in the right spots. It is made with five tailored foam layers, including a base layer with full perimeter zoned lumbar support right where I need it, and middle lay with premium foam and microcoils to create a soft contouring feel. Which also means if I feel like I want to sleep on my side, I can do that with without worrying about other aches and pains I might create. And with a luxurious pillowtop for pressure relief, I look forward to nestling into that bed every night that I use it. The best part of course is that it helps me wake up feeling fulst with a back that feels supple instead of stiff. That is the name of the game for me these days. Helix offers a 100 night sleep trial, fast free shipping, and a 15 year warranty. So check it all out. 20% off.

1:33:56 of all mattress orders by going to helixsleep.com slash Tim. That's HelixSleep.com slash Tim for 20% off all mattress orders. I have been fascinated by the microbiome and probiotics as well as prebiotics for decades, but Products never quite live up to the hype. I've tried so many dozens and there are a host of problems. Now things are starting to change and that includes this episode's sponsor, Seeds DSO1 Daily Symbiotic. Now it turns out that this product, Seeds DSO1, was recommended to me many months ago by a PhD microbiologist. So I started using it well before their team ever reached out to me about sponsorship, which is kind of ideal because I used it unbitten, so to speak, came in fresh.
