Yes. Taken together, **terminal lucidity, deathbed visions, NDE research, reincarnation cases, and some parapsychology/mediumship research form a much broader "mind beyond brain" research program**. But the evidential strength varies considerably between categories.
## 1. Terminal lucidity: the strangest phenomenon
**Terminal lucidity** is the sudden, temporary return of meaningful memory, personality, communication, and sometimes apparently normal cognition in someone with severe neurological impairment—often shortly before death.
The classic cases involve people with:
* advanced Alzheimer's disease
* severe dementia
* brain damage
* longstanding psychiatric or neurological illness
who suddenly become remarkably lucid.
For example, someone who has been unable to recognize family members for years may suddenly recognize them, converse coherently, recall personal memories, and then deteriorate again and die.
There is also the related phenomenon of **paradoxical lucidity**, where the improvement isn't necessarily immediately before death.
A 2023 review of the mind-brain question specifically discusses documented cases in Alzheimer's, dementia, schizophrenia and severe brain damage, noting that episodes can occur despite profound underlying impairment. ([Frontiers][1])
### Why it matters
The conventional neurological model says that memory and personality depend on functioning brain networks.
So if the brain is severely damaged, we ordinarily expect the corresponding cognitive capacity to be impaired.
Terminal lucidity raises an interesting question:
> **Could the damaged brain be suppressing or disrupting access to consciousness rather than producing consciousness in the first place?**
That's basically the philosophical distinction between a **production model** and a **filter/transmission model** of consciousness.
But there's an enormous caveat: terminal lucidity hasn't been studied nearly as systematically as dementia itself. We don't yet have continuous neurological measurements showing exactly what happens in the brain during these episodes.
A 2025 review of end-of-life experiences similarly concluded that terminal lucidity is striking but relatively rare and that rigorous studies with clinical controls and neuroimaging are needed. ([PubMed][2])
**Evidence level for survival:** intriguing, but currently **low-to-moderate** because the phenomenon itself is better established than its proposed explanation.

# 2. Deathbed visions and end-of-life dreams
This evidence is considerably more extensive.
People approaching death frequently report:
* deceased parents or spouses appearing to them
* deceased friends coming to visit
* deceased relatives welcoming them
* beautiful landscapes or light
* being told they are going somewhere
* preparing for a journey
* occasionally religious/spiritual figures
* extraordinarily vivid dreams involving deceased people
Importantly, these aren't exclusively NDEs. They can happen **days or weeks before death while the person is still conscious and interacting normally**.
A 2024 systematic review found **115 publications** on end-of-life experiences, with deathbed visions the most commonly used terminology. The most common experiences were visions or dreams involving deceased relatives/friends and themes of preparing for a journey. ([PubMed][3])
Another systematic review found that approximately **50–60% of conscious hospice patients** report some form of end-of-life dream or vision/visitation experience. ([PubMed][4])
And a 2025 systematic review found reported prevalence of end-of-life experiences ranging from **28% to 87%**, depending on the study and definition. Dreams and visions were the most frequently reported phenomena. ([PubMed][5])
### What's particularly interesting
They're often **not experienced as ordinary hallucinations**.
Patients frequently distinguish them from ordinary dreams and delirium. They may say:
> "That wasn't a dream."
The experiences can be exceptionally vivid and meaningful, and they are usually comforting rather than frightening.
The 2024 review found that the overall impact was predominantly positive. ([PubMed][3])
### But do they demonstrate survival?
No.
This is an important distinction.
A dying brain is undergoing enormous physiological changes. Medication, sleep disruption, hypoxia, metabolic abnormalities, expectation, memory and psychological processes could potentially produce some of these experiences.
The really interesting cases would be ones where someone obtains **verifiable information about a deceased person that they couldn't reasonably have known**.
Those cases exist in the broader deathbed/NDE literature, but they're much rarer and considerably harder to establish scientifically.

# 3. NDEs have become more scientifically interesting
This is probably the strongest bridge between conventional neuroscience and the "mind beyond brain" question.
The **AWARE-II** study, led by Sam Parnia and conducted across 25 hospitals, prospectively studied cardiac-arrest patients with EEG and cerebral oxygen measurements.
Of 567 in-hospital cardiac arrests:
* 53 survived to discharge
* 28 completed interviews
* 11/28 reported memories or perceptions associated with cardiac arrest
* 6/28 reported what the researchers classified as a transcendent "recalled experience of death"
Most remarkably, EEG patterns resembling organized brain activity appeared during CPR, in some cases **35–60 minutes into resuscitation**, despite severe cerebral ischemia. ([ScienceDirect][6])
That is genuinely important science.
But there's an important correction to some popular presentations of AWARE-II:
**It did not demonstrate consciousness operating without brain activity.**
In fact, one of the study's possible interpretations is that the EEG activity represents re-emergence of organized brain function during CPR. And the objective hidden-target tests were largely unsuccessful: nobody identified the visual target and only one participant identified the auditory stimulus. ([PubMed][7])
So AWARE-II establishes something like:
> **Conscious experience and organized brain activity can occur during a period of extremely severe physiological compromise that previously seemed incompatible with consciousness.**
That's fascinating, but it doesn't establish disembodied consciousness.
---
# 4. The reincarnation evidence is different
This is where the UVA research you asked about earlier becomes unusually interesting.
NDEs ask:
> **Can consciousness appear to function during extreme physiological disruption?**
Reincarnation cases ask:
> **Can information associated with one deceased individual appear in the mind of another person?**
Stevenson's and Tucker's children sometimes provide:
* names
* addresses
* family relationships
* occupations
* manner of death
* obscure biographical details
that subsequently correspond to a deceased person.
And some have behavioral characteristics, phobias or birthmarks corresponding to that person.
That is **a different evidential category** from NDEs.
And arguably it is more difficult to explain with a simple "the brain was temporarily deprived of oxygen" hypothesis.
---
# 5. Mediumship is another independent line
This is considerably more controversial, but there has been surprisingly sophisticated experimental research.
Some researchers have conducted **blinded mediumship experiments**, where the medium doesn't know the identity of the deceased person and the sitter doesn't provide information.
A 2021 meta-analysis of 18 experiments from 14 papers reported an aggregate effect above chance, with an estimated standardized effect of about **0.18**. The authors concluded that the results supported the possibility that some mediums obtain information about deceased individuals through unknown means. ([ScienceDirect][8])
That's interesting.
But this is also where I would be much more cautious than with the existence of NDEs or children's past-life reports.
There are serious methodological controversies in parapsychology, including replication, selective reporting and experimental design. A recent large-scale metascientific replication effort explicitly argues that stronger confirmatory methods have failed to establish the reproducibility of some famous psi effects. ([PLOS][9])
So I would **not** treat mediumship as established evidence of communication with the dead.
---
# 6. What "mind beyond brain" actually means
This is where the philosophy gets really interesting.
The standard **production model** says:
> Brain → produces consciousness.
Damage the brain → consciousness and memory disappear.
The alternative **filter/transmission model** says something closer to:
> Consciousness → interacts with/uses the brain.
Brain damage therefore might impair the **expression or access** of consciousness without necessarily destroying consciousness itself.
Think of the brain not as a television **creating** the broadcast, but as a television **receiving/filtering** it.
Terminal lucidity is potentially interesting because the "receiver" appears to function extraordinarily well despite severe physical damage.
NDEs are interesting because consciousness appears to occur during extreme physiological disruption.
Reincarnation cases are interesting because information seemingly associated with one person's life appears in another person's consciousness.
Deathbed visions are interesting because dying people sometimes report apparently autonomous encounters with deceased people.
And mediumship, if genuine, would be evidence that information associated with deceased persons can sometimes be accessed by living minds.
**That is why these phenomena are sometimes grouped under "mind beyond brain."**
David Presti's book *Mind Beyond Brain* explicitly brings together NDEs, apparent past-life memories, apparitions, death-associated experiences, telepathy, clairvoyance and precognition as evidence relevant to the question of whether consciousness can be reduced entirely to brain processes. ([Columbia University Press][10])

# My overall assessment
If we rank the evidence according to **how much I think it legitimately challenges a strict "brain produces everything about consciousness" model**, I'd roughly put it this way:
| Phenomenon | What is established | Challenge to materialism |
| --------------------------------------------- | ---------------------------------- | ----------------------------------- |
| **Deathbed visions** | Common, recurring phenomenon | 🟡 Modest |
| **Terminal lucidity** | Documented but understudied | 🟠 Significant |
| **NDEs** | Robust recurring phenomenon | 🟠 Significant |
| **AWARE-II physiological findings** | Conscious-like EEG during CPR | 🟠 Significant |
| **Children's past-life memories** | Large body of unusual cases | 🟠🟠 Strong |
| **Birthmark/death-injury correspondences** | Repeated unusual correlations | 🟠🟠 Strong but controversial |
| **Blinded mediumship** | Some positive experimental results | 🟠 Interesting but highly contested |
| **Proven consciousness independent of brain** | **Not demonstrated** | 🔴 Not established |
The really important thing is that **none of these phenomena, by itself, proves survival after death**.
But there's a cumulative argument that is much more interesting than any individual phenomenon:
**NDEs + terminal lucidity + deathbed visions + reincarnation-type cases + certain mediumship/psi findings**
are probing *different aspects* of the same fundamental question:
> **Is consciousness entirely produced by the brain, or does the brain somehow transmit, filter, localize, or constrain a consciousness that is more fundamental than the brain?**
And that's why I think your earlier comparison with the UVA reincarnation research is particularly fruitful. **The strongest reincarnation cases may actually be more evidentially relevant to survival than deathbed visions**, while **NDEs provide the strongest physiological challenge to the idea that conscious experience simply disappears whenever ordinary brain function is severely disrupted.**
The scientifically honest conclusion right now isn't *"science has proven an afterlife."* It's more like:
> **There is a substantial empirical anomaly surrounding consciousness at the boundaries of life and death. The evidence has not established survival, but neither has neuroscience demonstrated that the brain-production model adequately explains every important phenomenon.**
That's a much more defensible—and, frankly, more interesting—position.
