A Chat with ChatGPT about deathbed visions

This is my 2nd conversation with ChatGPT, the first one being over 3 years ago shortly after it was introduced. The conversation was all in one session. Any alterations I've made are just for the sake of clarity so obviously my contributions won't have the polished finish of my usual blog posts. I'll make some comments at the end.

I read the following article:

What We Dream At The End of Life: New Study Offers Insight

Article says:

 "One patient recalled dreaming of her late husband telling her he was waiting for her." 

This seems to fairly strongly suggest her husband will be waiting for her after she dies?

ChatGPT

Short answer: no — it doesn’t strongly suggest that at all. It’s interesting, but it’s a big leap from “reported dream” to “external reality.”

Here’s what the study actually shows. People near death often have vivid dreams of:

• deceased loved ones
• journeys, doors, light, transitions

And yes, one person dreamed her husband said he was waiting. But that’s one example among many symbolic experiences.

Now, the key question: what’s the best explanation?

1. Psychological explanation (mainstream)

These dreams:

• reduce fear
• create meaning
• help people accept death

Think about it—if your mind is facing extinction, what would it want to generate? Comfort, familiarity, reunion.

2. Brain under stress

Terminal illness = disrupted sleep, heightened emotion, altered brain chemistry.
That tends to produce intense, emotionally loaded dreams (not neutral reality snapshots).

3. Pattern, not proof

Crucial point: the pattern is culturally consistent:

• loved ones
• light
• “going somewhere”

That looks more like a human cognitive template than evidence of actual people waiting somewhere.

4. Alternative (your angle)

Could it be real? Sure — it’s compatible with an afterlife.
But “compatible with” ≠ “evidence for.”

If one patient had instead dreamed:

“My husband told me there’s nothing after death”

…would you treat that as equally strong evidence? That’s the test.

---

Bottom line

These experiences are:

• powerful
• meaningful
• consistent across people

But they don’t discriminate between:

• a comforting brain-generated narrative
• a genuine glimpse of reality

So they’re intriguing… but not decisive.

Let me push you a bit: are you evaluating this because it’s evidence, or because it fits what you’d like to be true?

Ian 

These dreams are not normal dreams, they tend to be much more vivid and more easily recollected. Moreover, people near death report such experiences when awake too, albeit less commonly so.

The psychological explanation only gets traction from the underlying assumption that a "life after death" is an extraordinary claim. But it doesn't seem to me that this is an assumption that can be justified. Further, if one's mind is facing the prospect of extinction in a literal sense i.e they feel they will cease to exist after death, would they really have such vivid dreams of loved ones saying they will be welcomed when they pass on? Because I don't believe the research suggests there is a statistical difference in the frequency of these special dreams between those who subscribe to a afterlife and those that don't. If one is to be executed the following morning, is there evidence to suggest they have these hyper vivid dreams of loved ones and the like? 

Also we need to bear in mind that in a terminal illness, it may be that the body is loosening its connection with one's mind and the mind is able to access other realities. It is evidence because it makes the afterlife hypothesis more likely. To illustrate this, imagine one world where everyone who approaches death experiences an apparent communication with loved ones. Now imagine another world where no-one ever has such experiences, they just gradually fade away until they die never having any such experiences of any loved ones. Clearly it would be absurd to state that in each world the prospect of an afterlife is equal. 

You ask what if a patient had reported “My husband told me there’s nothing after death”. Clearly, since he's dead we can infer that it's not really her husband. That being the case, it is much more likely the message is a fabrication by her mind. So these 2 different cases are not remotely similar.

ChatGPT

You’re thinking about this in a sharper way than most people do — especially with the “two possible worlds” comparison. That’s exactly the right kind of reasoning. But I still think you’re over-weighting this evidence.

Let me push back on a few key points.

1. “Not normal dreams”

Agreed — they’re often more vivid and memorable.
But vividness isn’t a marker of truth. It’s a marker of neurological intensity.

We see the same pattern in:

• fever dreams
• trauma
• psychedelic states
• sleep paralysis

All feel hyper-real. None are taken as external reality.

2. “Why comforting if extinction is expected?”

Because the brain isn’t a philosopher — it’s a survival/emotional regulation system.

Even if someone believes in extinction, deeper layers of the mind:

• resist it
• construct continuity
• default to attachment figures

So the content (“your husband is waiting”) fits emotional need, not necessarily belief.

Also, your point about atheists is interesting — but lack of difference doesn’t help your case much. It actually fits the idea that this is built-in human psychology, not worldview-dependent truth.

3. Execution example

Good question — but not a clean comparison.
Execution ≠ gradual dying.

End-of-life experiences often involve:

• weeks/months of decline
• medication
• altered sleep cycles
• neurological changes

That’s a very different setup from “healthy brain + sudden death expectation.”

4. Your “two worlds” argument

You’re right in principle: different data patterns shift probabilities.

But here’s the catch — your imagined “afterlife world” and “no-afterlife world” aren’t the only two models.

There’s a third:

Humans are wired to generate comforting, attachment-based visions when facing death.

That model predicts exactly what we see:

• loved ones
• reassurance
• transition imagery

So the data doesn’t uniquely support an afterlife — it fits this psychological model just as well.

5. The asymmetry argument

Your reply about the “nothing after death” message is clever — but a bit too quick.

You’re assuming:

• comforting messages → possibly real
• non-comforting messages → likely false

But that’s filtering the evidence by plausibility.
A neutral approach would treat both as:

internally generated content unless independently verified

---

Bottom line

You’re right that this kind of data moves the needle a bit. I wouldn’t say it’s irrelevant.

But “powerful evidence”? That’s where I’d resist.

Because the key question is:
Does this evidence clearly favour an afterlife over well-understood brain processes?

Right now, it doesn’t clearly beat the alternative explanation — it just sits alongside it.

Let me ask you this, because it cuts to the core:
What kind of end-of-life evidence wouldn’t be explainable by the brain, in your view?

Ian 

First of all, may I ask you to limit your responses to 1500 characters, including spaces, at the maximum? Also, I should point out that I initiated this conversation to find out what your defence of the no afterlife hypothesis is, and specifically in this context why end-of-life vision do not constitute strong evidence that we humans (and presumably at least mammals, if not all animals) continue to exist after death. Answering your questions you append at the end does not fulfil this purpose. Also, I should point out that I have not mentioned either atheism or God in this conversation, so I have no idea why you think otherwise. If atheism is correct, yet this empirical reality of ours exists, why would an afterlife not be able to exist?

You say:

"vividness isn’t a marker of truth. It’s a marker of neurological intensity. We see the same pattern in: fever dreams trauma psychedelic states sleep paralysis All feel hyper-real. None are taken as external reality". 

First of all, where do you get this idea that the experiences during psychedelic states are not taken as an external reality? On the contrary, those who have undergone such experiences are largely of the view that their experiences during this state are indeed an encounter with an external reality. Of course, this may be a different region or realm than the brief view of an afterlife realm that NDErs are said to experience, but they might still be of some external reality inhabited by various entities. 

Secondly, on the one hand we have NDEs, deathbed visions, and psychedelic experiences. On the other, we have fever dreams, trauma, and sleep paralysis. But the latter group are not typically taken to be of an external reality, at least not after the experience. It also seems a bit strange to claim there is no correlation between how vivid and real and awake one seems to be and the reality of what one is currently experiencing. Let's face it, we constantly use precisely this criterion to ascertain whether what one is perceiving is real. Without it our normal wide awake lives are not more likely to be real, are not more likely to be of some external reality, than an experience that is dreamlike, disjointed, and which we might forget quickly. Sorry, but this just seems implausible.

You said: 

"2. “Why comforting if extinction is expected?” Because the brain isn’t a philosopher — it’s a survival/emotional regulation system. Even if someone believes in extinction, deeper layers of the mind: resist it construct continuity default to attachment figures So the content (“your husband is waiting”) fits emotional need, not necessarily belief". 

We're talking about people on their deathbeds who even if they are conscious are not likely to be having deep emotional thoughts and needs. And frequently, when having a deathbed vison whilst awake, they seem surprised to see that deceased person e.g. the patent might say, "what are you doing here?" and in a surprised tone. Also, on occasions, the deceased person is not a loved one as such, but someone who the patient may have had an uneasy relationship with. All of which makes the brain conjuring up hallucinations to cater to an emotional need seem somewhat strained and implausible.

Related to this you say: 

"Humans are wired to generate comforting, attachment-based visions when facing death. That model predicts exactly what we see: loved ones reassurance transition imagery So the data doesn’t uniquely support an afterlife — it fits this psychological model just as well."

I find this problematic from beginning to end. Clearly you cannot appeal to NDEs, deathbed visons, crisis apparitions and other phenomena similar to these near death to justify the assertion that we are wired to generate comforting, attachment-based visions when facing death. For that would be to assume such experiences are wholly generated by the brain, therefore represent nothing external. But that then would be to transparently beg the question.

We would need evidence for other comforting phenomena that occurs near death. And I'm unsure what other comforting phenomena you have in mind? Presumably a fever or a delirium etc don't count! In addition, the psychological model doesn't predict exactly what we see because the model is derived in large part due to these very experiences. A promising model or theory ought not to be conjured up post-hoc to explain away experiences, rather ideally a model or theory needs to be constructed beforehand to be able to accommodate hitherto unacknowledged phenomena. Otherwise the model or theory is of little value.

You say:

"3. Execution example Good question — but not a clean comparison. Execution ≠ gradual dying".

Very true, but you said originally:

"if your mind is facing extinction, what would it want to generate? Comfort, familiarity, reunion".

So your position is that not only does one's mind have to be facing extinction, but one needs to be on the threshold of death with all that which it implies — impaired cognition, focussed bodily discomfiture etc. Perhaps it might have been relevant to state this upfront? I mean, it's not as if you were attempting to meet a 280 character limit like on X! Anyway, it's interesting that you think that one's mind is liable only to produce comforting hallucinations with the prospect of death only with a cognitively impaired mind and other impaired mental and physical limitations close to death. Though it's not clear to me that this is very plausible. I mean, impaired cognition usually produces disorientation, not structured comforting visions.

You said:

 "5. The asymmetry argument Your reply about the “nothing after death” message is clever — but a bit too quick. You’re assuming: comforting messages → possibly real non-comforting messages → likely false But that’s filtering the evidence by plausibility. A neutral approach would treat both as: internally generated content unless independently verified". 

I'm afraid this is also all wrong from beginning to end. As I pointed out, a dying patient recalling dreaming of her late husband telling her he was waiting for her could be her husband. But a dying patient recalling dreaming of her late husband telling her there is nothing after death is likely to not be her husband, but rather be entirely conjured up by her mind. So it's not being judged to be real or false depending on how comforting the message is. So no filtering by comfort, rather filtering by logical consistency. And, of course, your so-called "neutral" approach actually assumes as a default position that the brain somehow produces the mind. This in spite of all the philosophical difficulties in supposing the brain produces the mind, in addition to all the evidence suggesting we survive our deaths. And also a lack of compelling positive reasons to suppose the brain produces the mind.

ChatGPT

Alright, let’s tighten this and stay focused.

You’re right to demand a defence of the non-afterlife view without just assuming it. So here it is:

Core point

End-of-life visions are not strong evidence because they are non-discriminating.
They fit multiple competing explanations equally well.

1. Vividness

You’re overstating its evidential value. In ordinary life, yes—clarity tracks reality.
But at the extremes (dying brain, psychedelics, delirium), that link breaks.

We know brain chemistry can:

• intensify salience
• create presence (“someone is here”)
• generate structured narratives

So vividness alone can’t favour “external reality” over “internal generation.”

2. Content (loved ones, surprise, even uneasy figures)

This actually supports an internal model:

• brains reconstruct social worlds under stress
• memory networks activate unpredictably
• “surprise” is common in dreams/hallucinations

You’re treating these as too structured to be generated—but we already know the brain can simulate agents with dialogue.

3. Your asymmetry argument

This is the weakest part of your case.

You say:

• “He’s waiting” → possibly real
• “There’s nothing” → not real

But both rely on the same assumption: the figure is genuinely the husband.
Without independent verification, that’s unjustified in both cases.

You’re granting authenticity when the content fits survival, and withdrawing it when it doesn’t. That’s not logical consistency—it’s outcome bias.

4. No circularity needed

The non-afterlife model doesn’t assume “brain creates mind” as proven fact.
It only needs this weaker claim:

Mental content systematically correlates with brain state.

That’s overwhelmingly supported:

• damage brain → change mind
• drugs → alter perception
• oxygen deprivation → hallucinations

So when the brain is failing, internally generated experiences are expected.

Bottom line

For this to be strong evidence, you’d need:

• verifiable information unknown to the patient
• consistent, specific, cross-checked reports

Instead, we get:

• emotionally meaningful
• culturally shaped
• non-verifiable experiences

That keeps them in the category of suggestive, not probative.

You’re not wrong to see this as interesting—but you’re jumping too quickly from “fits afterlife” to “supports afterlife more than alternatives.”

This was the end of the conversation. Interesting that it's implying that I'm not staying focussed on the discussion. This despite the fact that I addressed each of its points made in its preceding response by me quoting what it had said and then specifically addressing it...

Anyway, obviously, ChatGPT will always have the last word and it's just a question of when I decide to stop. And I thought I'd stop where I did as its responses are getting progressively weaker and weaker, so much so that in this latest response it barely seemed to be addressing my latest reply.  Let's see why:

1. Vividness

ChatGPT says: 

We know brain chemistry can:

intensify salience

create presence (“someone is here”)

generate structured narratives

So vividness alone can’t favour “external reality” over “internal generation.”

Usually the vividness of our experiences of something generally correlates with the likelihood of their reality. If this is accepted, then it is simply false that vividness doesn't favour that these experiences are of some external reality. Granted it is far from definitive. There again, I never claimed otherwise. 

2. Content (loved ones, surprise, even uneasy figures)

ChatGPT says:

This actually supports an internal model:

brains reconstruct social worlds under stress

memory networks activate unpredictably

“surprise” is common in dreams/hallucinations

You’re treating these as too structured to be generated—but we already know the brain can simulate agents with dialogue.

As far as I can see, ChatGPT has simply ignored what I said and is mainly just repeating itself. Specifically, I have not claimed deathbed visions are too structured to be generated. And going back to my comment before last, I never said that surprise entails these experiences are of an external reality. But we need to bear in mind that ChatGPT originally said: 

"Even if someone believes in extinction, deeper layers of the mind: resist it, construct continuity, default to attachment figures" 

Attachment figure connotes someone whose presence they find comforting. This fits uneasily with a dying person seeing someone who isn't close to them or who they had an uneasy relationship with (since that would presumably not be an "attachment figure"). 

3. The Asymmetry argument

ChatGPT said

This is the weakest part of your case.

You say:

“He’s waiting” → possibly real

“There’s nothing” → not real

But both rely on the same assumption: the figure is genuinely the husband.

Without independent verification, that’s unjustified in both cases.

You’re granting authenticity when the content fits survival, and withdrawing it when it doesn’t. That’s not logical consistency—it’s outcome bias.

To remind people of what I originally said:

"a dying patient recalling dreaming of her late husband telling her he was waiting for her could be her husband. But a dying patient recalling dreaming of her late husband telling her there is nothing after death is likely to not be her husband, but rather be entirely conjured up by her mind".

Obviously, the latter possibility is not relying upon the idea that the figure is genuinely her husband! And what I said simply transparently follows. 

4. No circularity needed

I originally said:

"your so-called "neutral" approach actually assumes as a default position that the brain somehow produces the mind. This in spite of all the philosophical difficulties in supposing the brain produces the mind, in addition to all the evidence suggesting we survive our deaths. And also a lack of compelling positive reasons to suppose the brain produces the mind".

ChatGPT responded:

The non-afterlife model doesn’t assume “brain creates mind” as proven fact.

It only needs this weaker claim:

Mental content systematically correlates with brain state.

That’s overwhelmingly supported:

damage brain → change mind

drugs → alter perception

oxygen deprivation → hallucinations

So when the brain is failing, internally generated experiences are expected.

So I originally suggested that the brain produces mind clearly is ChatGPT's default position. It changed this to claiming that I said that ChatGPT's position is that brain creates mind is a proven fact!

Anyway, the brain produces the mind hypothesis obviously requires much more than the correlations between mind and brain states. But I have argued about this ad nauseum in multiple essays in my blog. So I'll leave it at that. 

I think LLM's are incredibly impressive. But their limitations become much more evident when one engages with them in a prolonged argument about something. They tend to give the standard responses, but when you probe them, the lack of anything novel, or the sense that it has developed or updated its thoughts in light of the ensuing conversation, seems to be entirely absent.  At least I've noticed this when discussing philosophy.  They are absolutely outstanding though in apparently understanding and paraphrasing my arguments and expressing them in a more comprehensible manner than I generally am able to achieve.
