Interesting story, thanks for sharing.
I think we can only gauge situations like these on probabilities, i.e. what is more likely? Is it more likely that someone is stepping into the afterworld and conversing with dead souls? Or it more likely that the brain is under duress and causing visual phenomena?
I can't claim to know either way, but I usually lean on what is more probable.
Just some kindly advice......dont put to much stock in this brain stress/visual explaination.
Some kindly advice... arguments help get points across.

Really though, it's because it's just a funky brain experience. I think it does serve a purpose. It creates an illusion of a greater reality...those who "come back" can help us to be more at ease with existence, and our inevitable demise. The groups who had these experiences could cope better, and be more resilient to stress...giving them an evolutionary advantage.
I'm not that weak. No need for hocus pocus here.

Well I didnt want to agrue about this topic. We have folks with very bad injury for example, telling us they died or started to drift over. Saw some things heard some things. We should pat them on the head and say "now now Dorothy you just took a hit on the head"?
Now from a scientific point of view, if brain stress visual/audio......whatever.... were worth considering then there would be a large body of evidence of it producing like conditions in folks under great stress but not death, maybe near it.....but theres not.

So, from my own experience... this concept of disorientated thinking and amnesia might not be something localized to my own experience and offer that it might be universal to the experience. IE many people who say they didn't have one simple don't remember it.
Plausible but not definitive.

No thanks!
My beliefs are quite different
Did you know that the experience of NDE depends on the culture, and/or religious beliefs or lack there of from the individual?
hmmm, I wonder what we can conclude

There was actually an ATS debate about this recently. One I argued the "pro" side of, as I have had an NDE. One aspect that I did not discuss in that debate, however, was that I suffered a side effect of my near death called transient amnesia. I can remember bits and pieces of the experience - but nothing for the hours prior to the cardiac arrest that cause my NDE ( I have filled in those gaps because I was around other people, and was told what I'd been doing in the hours leading up to my event. ).
But as for the 20 to 30 days after it? I can only remember very few fragments.
I was in the hospital for at least two weeks before I even realized that being in a hospital wasn't normal or customary.

Human Consciousness and the Personality Trajectory
The notion of the dynamic hybrid (event and information) trajectory that I refer to as The Personality is central to the entire process that differentiates what constitutes a corporeal human being from all other forms of life that are equipped with a brain. While it may be easy enough to assert that such a trajectory exists, what is more difficult is proving that The Personality hybrid trajectory exists. In fact, it may ultimately be impossible – given our present technological capacity to perceive such a thing – to prove the physical existence of The Personality trajectory by way of specifically identifying it and separating it out from the overall system that includes it and the process that it enables as a result of its inclusion.
Still, that process can be examined, and there may be ways of inferring its existence if we examine this process from a perspective that allows for its (The Personality’s) existence. Of course, this can’t be offered as definitive proof, but it might go a long way toward increasing the plausibility that such a dynamic process does exist, and possibly even allow us to further identify relatable aspects of The Personality and how these aspects might provide their own level of inferred verification that this process does, in fact, exist regardless of the specifics concerning how the process itself is accomplished.
The first part of this examination focuses on the creation of consciousness as a brain process, with a look at one theory concerning how this event happens. I’ve chosen this theory due to the fact that it is fairly indicative of a strict materialist concept where the brain itself manufactures the consciousness stream as definite bursts of information events. My affinity with this overall concept is due primarily with its obvious alignment with other established tenets concerning the nature of physical reality involving the event unit as a basis within any development arrangement – specifically Planck’s Constant, in this case.
Professor Susan Greenfield (Oxford University) has proposed that the mind may arise from the activity of brain cells at the level where the cells are connected together (the synapses). Rather than arising from a single isolated region of the brain, she suggests that consciousness arises diffusely from the brain-cell connections.
The reasoning, Greenfield argues, is that there is no single complete function that takes place in one region of the brain. As mentioned above, it is known, for example, that vision is divided up into many separate components that are connected together to give rise to the conscious experience of seeing, such as color, motion, and form processing, and the function of vision can preoccupy over 30 brain regions. So brain regions are smaller parts of a wider brain stage and not units that work alone. Thus we know that conscious experience arises from the actions of many different parts of the brain.
However, when we break each area of the brain down into its smaller constituents, we see that each area is a complex circuit that is ultimately reduced down to the connections between the cells, or synapses, or in other words, to the individual wires of the circuits themselves across which electrical signals are passed. This signaling is dependent on a series of different biological products, or proteins, which are themselves products of genes. Therefore, Professor Greenfield has proposed that the neuronal correlate, and in effect, the physical substrate of the "mind" is a process that occurs at the level of the brain connections, or synapses, which are not only highly dynamic, but which also reflect experience through their strength and extension of connections.
According to this theory, consciousness, or our sense of self-awareness, is thought to arise from the interaction of assemblies of neurons involving up to tens of millions of neurons all connected together. It is proposed that at any one time, there may be many neuronal assemblies present; however, the largest assembly will dominate and determine that moment of consciousness.
The degree to which cells are recruited, and hence the degree of consciousness, will be determined by a variety of factors, such as the strength of the input coming into the brain - for example, from the eyes and the fingers, as well as preexisting connections and the degree of competition, as shown by the smaller assemblies starting to form. (excerpt - WHAT HAPPENS WHEN WE DIE: Sam Parina MD)
So, it's the word competition that catches my eye here. Is Parina suggesting that Greenfield's theory rests upon the idea that these sub-assemblies actually compete for primary influence within the corporeal brain's function as the generator of human consciousness? Maybe, if I read on, his interpretation of Greenfield's theory will reveal that choice of "competition" as an operative description to be a quick slip, and not integral to this specific theory concerning the brain's actual configuration of conscious awareness per specific instant within a defined chain of causation.
So, let's imagine that we're standing on the street holding something in one hand. An assembly of brain cells related to "touch" is active, so we're aware of what we're holding. Then, suddenly, we see something that interests us - for example, an accident. We then stop feeling what we're holding and just experience what we're seeing. At that time, the activity of the assembly of brain cells related to touch would be overtaken by the new assembly of cells, which would have become active in relation to what we have seen.
The activity of these cells is in turn determined by the activity of various proteins, which may change in response to other signals, including events taking place in our body, such as hormone changes, immune changes, or changes in the levels of neurotransmitters. So in the same scenario, if we had the flu and were feeling very ill, certain chemicals and hormones would be released by our body and immune cells that would also interact with the brain cell networks, so we would feel "unwell" while seeing an interesting event.
It has thus been suggested that the subtlest influences either from outside or inside the body modulate consciousness at the level of cell synapse in the brain, and hence, lead to differences in consciousness, and that there’s always a competitive process going on between different assemblies of cells.
Okay, so it does seem to be Dr. Parnia's interpretation that this process is the result of cell assemblies winning within a competitive environment, with external impetus launching a literal scramble for assembly dominion within a theater of many such assemblies poised at the ready for their chance to take the helm. As this excerpt is taken from a traditionally published work of non-fiction, I'm going to assume that Prof. Greenfield's theory has been accurately described by Dr. Parnia, including his own use of that theory as the basis of the specific vignette he offers as further clarification of how Greenfield's theory translates to real world moments. I generally find that rephrased presentations (if allowed by the theory's original author, of course) give me a slightly better view of the theory itself, so I'm going to use Dr. Parnia's interpretation of Prof. Greenfield's consciousness theory in this examination. Especially since it's probably not absolutely critical that I deal with every minute aspect of that theory here. In fact, my issue with it focuses on not what's been stated here, but what has been neglected. In that sense, the minute specifics of Prof. Greenfield's theory are not even germane to this examination at all, and Dr. Parnia's broad overview will serve nicely to set up the premise.
Managing the Initiation of Perception
What we have here is a biological process that is a reaction to an event chain that impacts the bio-logical holon that is being managed by the brain and the ultra-sophisticated neural functionality that comes together to be that brain as a functional whole. Now, while I have to agree that the connection (synapse) network reaction (as a definite event involving concurrent and consecutive exchanges of in-formation signals) is very likely the "burst" of intellectual response that we're seeking when looking to define the emergence of consciousness, what is missing here is the means by which response requirement is presented to the brain's entire assembly community, and the management process involved in the brain's choice of which assembly will be activated to the level of dominating the sentient experience and for how long that dominance will last.
What is clear is that consciousness - intellectual self-awareness - did not evolved casually as a capacity within the corporeal brain. Descriptions of the depth and breadth of complexity and precision involved in the simplest of structural responses to mundane events suggests that the sentient brain evolved as a result of specific requirement. After all, nothing just emerges within the material realm. Opportunity can explain how something developed, but it can't explain why it developed. Requirement is the impetus for what comes into material existence, and when examining requirement, if you dig down deep enough, what you're left with is survival, and that's all your left with. Whatever else you find is directly associated with survival and filling the role of defining specific expressions of survival (or the most effective and efficient means of achieving survival). When addressing the development of something as epitomical as the human brain (for instance), the fact that survival of the identified whole is the primordial driver involved in that development infers that certain criteria be met while achieving that development. It also infers that some specific aspects integral to the developed end product be avoided, since survival itself is the achievement being sought.
Abraham Lincoln once wrote that "a house divided against itself cannot stand", and he was correct about that observation as it pertained to the Union. Within the corporeal whole that is the body, this observation is also correct. In fact, the destruction that such a schism creates is much more immediate within the corporeal body than it could ever be within the union of states that Lincoln was addressing with his statement. More immediate and much more impossible to unwind as progressive ramification that will continue as more and more of what results, reacts to what has been initiated. If the human brain's response to external and/or internal stimuli was actually based on a free competition between cell assemblies that (as any brain/mind researcher will admit) are completely incapable of independent sentience (let alone human judgment) then the survival imperative could not have been the driver that led to its development. To even suggest that simple chemical triggers and hormones make the decisions concerning what the conscious mind will perceive as not only significant, but even apparent, is to grant these chemicals and hormones a level of intellectual capacity that no one is willing to acknowledge.
So, what is the management activity involved in the triggering of conscious awareness as a survival response to the issue of corporeal existence within a competitive environment? For that, we need to take a look at the nature of information as a physical reality, and the possibility that there are more versions of information than raw data that simply represents the occurrence of activity and being.
What we do know is that DNA provides survival directives within each cell of virtually all living things. I say virtually because of what’s known about specific pseudo-organisms called prions which appear to accomplish dynamic existence without DNA, but that’s another issue entirely. DNA provides default protocols that have been established by a process of progressive development specific to the organism and its species’ history. Successes and failures have established the unique precedence chain, with the DNA itself as the informational account concerning what succeeded and – by its absence – what failed to succeed. In the brain-equipped organism, this information is what the brain translates into specific and detailed action items to be divided out and delivered to the assemblies and sub-assemblies that make up the corporeal whole that is the whole body of the organism itself.
So, basically, the management function is fairly simple and somewhat apparent, and species behavior is relatively consistent even among the more sophisticated organisms that employ this basic management system. We have labeled this system natural instinct, and even the most sophisticated of brain-equipped mammals are largely driven by natural instinct. The truth is that even if personification can bring out unique personality traits as apparent to human perception, in the end, a dog will always resort to breed, and this is the point. Natural instinct, the impact of DNA as the primary management driver, is what generally governs the generation of dynamic information “action items” within the corporeal brain. The sophistication and nuance capacity – regarding the translation of the DNA’s broad directives – provides the only real differentiation between one species intelligence and the next.
