A couple of weeks ago, Dr. Sam Parnia released a new mini-documentary about Near Death Experiences (NDEs), which he now coined a new term for: REDs, for 'Recalled Experiences of Death.' His argument is that, physiologically, these people weren't merely near death, but actually died and were resuscitated thanks to modern medical technology. Indeed, defining death as a state one can never return from is operationally contingent; it is arbitrary and ignores the physiology—the science—of the process. So I am comfortable with the term RED.
But I diverge. The point of this essay is a common feature of REDs and 'Out of Body Experiences' (OBEs) that have always stricken me as exceedingly odd: the claim by experiencers that they could perceive the colloquially physical world around them—from a mildly elevated, bird's-eye perspective—during the period of, e.g., cardiac arrest, as if they still had working eyes and ears. This seems to violate logic, as evolution required hundreds of millions of years of painstaking adaption to come up with retinas and eardrums. And that these are needed to perceive the world is unquestionable: right now, if you close your eyes and ears, you will see and hear nearly nothing. So how can a patient under cardiac arrest, lying on a hospital bed with eyes closed, see and hear what is going on in the corridors outside their room? If one can see and hear perfectly well without working eyes and ears, why do we need them at all? Why can't I close my eyes right now and see what's happening around the corner of my street?
Nonetheless, I am not one of those people who find it easy to disregard (anecdotal) evidence just because it doesn't fit with their understanding of the world. As a friend reminded me of just a couple of days ago, alluding to a particular scene from the Netflix series Chernobyl, theory must fit the facts, not the other way around. And there are just too many mutually-consistent reports to dismiss. My commitment to truth is such that I just can't pretend otherwise, which puts me at an impasse, for I am equally unable to think of nature as something so capricious as to change the rules of the game on a whim. I just can't accept that eyes and ears are utterly unnecessary to perceive this world during a RED or OBE, but absolutely necessary during ordinary waking states. Moreover, nature just isn't so redundant as to struggle for hundreds of millions of years to evolve retinas and eardrums we can allegedly do perfectly well without.
The present essay is the result of my struggle to make sense of this conundrum. At this stage, however, what follows is still very highly speculative and should be taken with a whole bag of salt. I am not at all committed to the conjectures I discuss below, but simply play with them as an intellectual exercise. In the future, I may further expand on these thoughts in a more rigorous manner, if my argument can be more substantiated. Alternatively, I may abandon the idea altogether. Either way, right now what follows is just a very loose exercise of theoretical imagination, nothing more.
Finally, notice also that the Phantom World Hypothesis is supposed to cover only the parts of a RED or OBE that seem to relate directly to the ordinary, so-called physical world; not the parts about transcendence and other realities.
Assumptions
I am not a RED/OBE researcher or scholar. My interest in these states is professional but ancillary. Therefore, I must start with some basic assumptions, knowing full well that these may ultimately prove to be wrong or misleading. My assumptions are these: (a) experiencers of REDs/OBEs are being sincere and reasonably accurate when they report the ability to perceive the ordinary, colloquially physical world during the period in which they do not have functioning sensory organs; (b) Nature indeed isn't redundant or whimsical, so despite their sincere reports, experiencers in fact aren't truly perceiving the colloquially physical world around them.
Background
I will base my hypothesis on the tenets of my own Analytic Idealism. According to it, all nature consists of experiential—i.e., mental—states. Some of these states are within our individual minds, such as our own perceptions, thoughts and emotions. We identify with these internal states or at least feel that we own them. Other mental states in nature are external to our individual minds and, therefore, constitute the external environment we inhabit. I shall say that these external mental states belong to a 'mind-at-large' beyond our individual minds.
That there can be mental states out there, outside your individual mind, is nothing new: my thoughts are mental, and yet external to your mind. Analytic Idealism simply leverages this trivial fact to argue that the entire world beyond the boundaries of our own minds is constituted of external mental states as well, not just the inner lives of other people.
When external mental states in mind-at-large impinge on our individual minds, they modulate our internal mental states. This is what we call perception: what we see, hear, taste, smell, and touch are our inner representations of external states. As such, under Analytic Idealism there is indeed an external world beyond us; a world that does not depend on us to exist or do whatever it is that it does. When we interact with this world—such that the world impinges on us—its states are represented by our individual minds as the colloquially physical world around us. As such, what we perceive is merely an image, an appearance of states in mind-at-large.
Still under Analytic Idealism, what separates our internal mental states from the external mental states of mind-at-large is a dissociative boundary. Just like the multiple, disjoint personalities—called 'alters'—of a patient of Dissociative Identity Disorder (previously known as 'Multiple Personality Disorder'), each living being is a dissociative alter of the field of mentation that constitutes nature. A biological organism is what one such an alter looks like when represented on the screen of perception. Biology, life, is the perceptual appearance of a dissociative alter in the universal mind we call nature.
As such, death—the end of life—is, in fact, merely the end of the dissociation, of the alter, not the end of consciousness. The dying process is that by which the previously private mental states of the alter—one's personal memories, insights, etc., originally insulated from their cognitive surroundings by a dissociative boundary—become progressively re-associated with the mental states of mind-at-large. It stands to reason, thus, that this should be experienced as an expansion of consciousness, not its end, which is precisely what experiencers of REDs/OBEs report.
The Phantom World Hypothesis
Among the previously private mental states of an alter undergoing re-association—i.e., a person dying, being re-integrated into his or her cognitive surroundings—are episodic memories. These contain a lifetime of perceptions: a cognitive map of one's home, neighbourhood, city, country, places visited or seen on TV shows and YouTube videos, and so on. We don't just perceive the world, we also remember these perceptions. As these perceptual memories accumulate over time, they form an increasingly broad, high-resolution, internal map of our environment, constituted of the qualities of perception: the colours, shapes, contours, and geometrical relationships that define what we colloquially call the physical world. Even when you are lying in bed at night, with your eyes closed, you can access these perceptual memories to visualise your room, your street, the route to work that you will be taking in the morning, etc. As such, a copy—more or less precise, more or less accurate, more or less comprehensive—of the world as perceived exists in us at all times.
When we die, this copy of the world as perceived and remembered becomes re-integrated with the external mental states of mind-at-large. And since people are dying every minute, mind-at-large becomes increasingly enriched with individual perceptual maps, which are representations of its own states. These perceptual maps—each corresponding to the perceptual memories of a re-integrated alter—become cognitively associated with one another, like different pieces of a giant jigsaw puzzle coming together. It is reasonable to infer this because we know that this is how mind works: through spontaneous cognitive associations based on similarities and correspondences. Mind-at-large cannot help but spontaneously put the pieces of the puzzle together.
Nature's mind is thus constantly assembling a cognitive map of itself—a jigsaw puzzle representing its own states, whose pieces are constituted of qualities of perception—based on the episodic memories it inherits from re-integrated alters. Where there are gaps, extrapolations spontaneously arise, just as we extrapolate our own perceptions to infer that, say, a wall partly obscured by a tree in fact continues behind the tree; or that a road continues beyond the visible horizon; etc. These extrapolations reflect well-known and intrinsic properties of mentation: you spontaneously extrapolate a square from the figure below, even though there is no square in it at all; you do it because this is what mind naturally does. Technically called interpolations, the extrapolations complete the jigsaw puzzle where pieces are still missing. The result may be an inaccurate but rather complete cognitive map, a Phantom World constituted of perceptual qualities originally generated by living people and other organisms.

I call the resulting map a Phantom World because mind-at-large isn't actually perceiving the world; it isn't actually representing its own states on a screen of its own perception. Instead, it is merely inheriting the perceptual states of myriad former alters and spontaneously assembling them together through cognitive similarity and correspondence. The resulting pseudo-perceptual world is thus an approximation containing inaccuracies and imprecisions (the interpolations). Nonetheless, it should still feel as though it were a (colloquially physical) world perceived, since it is made of qualities of perception like the colours and sounds you and I see and hear.
During a RED or OBE, I contend that the dissociative boundary that defines the individual mind of a person becomes weakened, porous, permeable, allowing for partial but direct access to external states in mind-at-large, without the intermediation of a screen of perception. And since these external states contain the Phantom World, the experiencer gains temporary access to that pseudo-perceived world.
I suggest, therefore, that the experiencer is not actually perceiving the real world, but the Phantom World instead. For this, the experiencer indeed does not require working eyes or ears, for he or she is accessing the compound result of myriad episodic memories—the assembled jigsaw puzzle—of people who did have working eyes and ears. Analogously, when you are lying on your bed at night, with your eyes closed, visualising your route to work the next morning, you too can visualise it by recalling episodic memories and without using your eyes.
Perspectival transposition
A number of possible criticisms of this hypothesis must be popping in your mind right now. I will try to anticipate and address them in this and the next sections.
The first issue is the perspective experiencers report: a bird's-eye view of things, as if they were floating above other people, the furniture, the cars on the streets, etc. This perspective does not correspond to the episodic memories of any human being, dead or alive, since we don't ordinarily float around like air balloons. How can this be accounted for under the Phantom World Hypothesis?
Even in ordinary waking states, our minds routinely adjust our perceptual experience so to conform to an expected context or perspective. In other words, we don't just perceive the world as it is, we manipulate our perceptual states so they fit with the context we cognitively expect. This is so even when you know what is going on. In the picture below, for instance, the squares marked A and B have exactly the same colour. Yet, because the context forces you to expect them to have opposite colours, that's what you see. And you will continue to see it even after you convince yourself that the squares do indeed have the same colour.
The drawing below contains a variety of perspectival illusions. Even after we realise that what we think we are seeing is impossible, we continue to see it nonetheless. This is an intrinsic property of mind: it tries to fit what it perceives to its expectations and models of what is going on.
There are countless other compelling examples of our minds imposing a perspective onto the contents of perception that is not there at all. The video below is just one more example, where we impose very specific movement where there is none. And even knowing this, and being convinced of it, does not reduce—let alone eliminate—the seeming perception.

My contention is thus the following: during a RED/OBE, the experiencer expects to perceive the world from his or her own unique and contingent point of view, not the objective perspective of other people, dead or alive. To reconcile his or her access to the Phantom World with this expectation, the experiencer transposes his or her experiential vantage point accordingly, thereby generating the bird's-eye view. This is possible because the Phantom World is already a cognitive model—an interpolation—anyway, so any perspective can be 'computed' from it through a form of grounded, calibrated imagination.
Ongoing experiences
Another issue with the Phantom World Hypothesis is that experiencers often report, veridically, what is going on in the world during the RED/OBE: what people are saying, doing, etc., while the experiencer is in, e.g., cardiac arrest. This means that their pseudo-perceptions cannot be grounded only in the episodic memories of the deceased, but also in the ongoing experiences of living people, as they unfold.
Under Analytic Idealism, the mental inner lives of two different people are ordinarily separated from one another by two dissociative boundaries, each defining the limits of each person's individual mind. During the RED/OBE, however, we've hypothesised that the dissociative boundary of the experiencer becomes weaker, porous, permeable. As such, it is reasonable to conjecture that access to another person's on-going experiences becomes easier than under ordinary circumstances. This is especially so if those other people are emotionally connected with the experiencer, which could spontaneously shift their own state of consciousness in a manner that weakens their own dissociative boundary as well.
If this direct mind-to-mind access does take place, it is in principle reasonable to conjecture that the experiencer will import it into the Phantom World—to keep everything consistent and unified—and again spontaneously apply a perspective transposition, as discussed in the previous section, so to portray such access as if it were taking place from an external vantage point. After all, the experiencer doesn't expect himself/herself to be another person. Instead, things will be experienced as if he/she were seeing or hearing another person. The experiencer will then report having seeing or heard other people say or do this or that, while, in fact, the experiencer has directly accessed their inner mental states.
Implications and validation
To check whether the Phantom World Hypothesis is consistent with the (anecdotal) RED/OBE data, we must derive its implications and check them against what experiencers report. So let us do this, one implication at a time.
If some of what is reported corresponds to direct access to the inner mentation of living people—subsequently transposed to an external perspective—then experiencers should, at least occasionally, report accessing endogenous mental states of others as well. In other words, in addition to knowing what people said or did, experiencers should, at least occasionally, claim that they knew what people were thinking or feeling. And indeed, this is precisely what is often reported. In the recent mini-documentary by Dr. Sam Parnia, linked above, an experiencer claimed to have become aware of what his doctor was thinking—a claim confirmed by the doctor—while the experiencer himself was in cardiac arrest. If the experiencer can access someone's thoughts, than she or he surely can access what one is seeing, hearing, or otherwise perceiving. This corroborates the hypothesis that experiencers aren't actually perceiving the real world without functioning eyes or ears, but pseudo-perceiving the world by proxy, through the inner mental states of both the deceased and the living.
Another implication of the Phantom World Hypothesis is that, since the Phantom World is a cognitive construct, a model containing interpolations and extrapolations, at least occasionally experiencers should report things that don't actually match with the real world. These inaccuracies are probably filtered out in the popular literature, since they can easily be (mis)interpreted as refuting the validity of the RED/OBE. Yet, under the Phantom World Hypothesis, occasional inaccuracies and oddities are precisely what one would expect. These inaccuracies—provided that they are localised within a broader context that is itself veridical—in fact corroborate the validity of the RED/OBE.
Finally, the most important implication of the Phantom World Hypothesis is this: the experiencer should not be able to know any fact that has never been experienced by any organism still alive or already dead. Because the hypothesis entails that experiencers only pseudo-perceive the world—that is, perceive by proxy, through the inner mental states of others—whatever no one has ever perceived or otherwise known cannot be accessed by the experiencer. As such, when Dr. Sam Parnia devised his famous experiment to test the veracity of REDs—wherein he placed electronic displays on top of tall cupboards, facing up and displaying random numbers automatically chosen by a computer, to see if the 'free-floating soul' would be able to read the numbers—he ensured that no experiencer would succeed. After all, the experiment was designed to be double-blind: the experimenters themselves didn't know what numbers were displayed. Therefore, no one, dead or alive, knew what the numbers were. It was impossible for the experiencers to access such information, since their access is always by proxy and not direct. The experiencers don't have eyes to perceive the displays; they can only see what others see or have seen. Again, this implication of the Phantom World Hypothesis seems to match with the data, as Parnia's experiment is known to have 'failed.'
Conclusions
The Phantom World Hypothesis should not be taken as a rigorous scholarly theory, for it is no such thing; at least at the present time. As it stands, the hypothesis is merely educated speculation and conjecture, with very little theoretical underpinning or empirical basis. But the little it does have is, well, a little intriguing.
I am not an experimentalist in the field of REDs/OBEs. I cannot, therefore, take it on myself to design and carry out experiments to validate or falsify my own hypothesis. But those who are in the position to do so could perhaps allow themselves to be informally informed by the Phantom World Hypothesis in their experimental designs. Doing so would prevent the understandable but possibly equivocated jump to concluding that Parnia's experiment debunks the veridical aspect of REDs, for its very double-blind design could have precluded any veridical report.
New experiments are needed that are informed by the Phantom World Hypothesis.
