Abstract
The cognitive and perceptive characteristics of 70 cases of Near Death Experiences have been studied. The detailed analysis of the unusual modes and characteristics of spatial and temporal perception during these experiences reveals a "hidden" logic for which I propose a model where the point of perception would be in an extra dimension. The appropriateness of such a model is analyzed and shown to be consistent with the NDE accounts in the study. In contrast, those interpretations of such perceptions as being purely hallucinatory are undermined. Whatever its meaning, the underlying logic shown in this study suggests that NDEs seem to follow precise rules. Since these experiences can be viewed as an unusual but consistent behavior of consciousness, they deserve further pluridisciplinary study.

12.1. Past, present, future, all confused If we walk on a lane, one part of the way is behind us, another is ahead. But if we see this lane from above, no more walking on it, not only are we nowhere on it but also, as they were relative to us, the notions of behind and ahead logically disappear. In the same way, if we are "out of time" we are no more subject to its arrow. Thus the notions of past, present and future can disappear or merge together. In fact, almost every feature we are about to review seems to translate a spatialization of time:
Past, present future are merged in a single concept, that's what I experienced (X.S.) Time no longer existed, past, present, future, all confused. (M.O.)
No sensation of duration, neither of waiting. No sense of past, present, future, as if all that was away from me. (F.E.)
During NDEs, frequently following the OBE stage, most patients describe a "life review". They report having been able to "see" or sometimes "live again" some moments or only significant scenes of their life, in chronological order or in reverse order. During this stage some additional anomalies and perspective effects concerning time will appear, strengthening the hypothesis that our universe could be perceived from an external vantage point.
12.2. Flying over time The non-locality of the observer in relation to the observed universe, which has helped us understanding the spatial 4D perspective effects appears to concern also time: to be "outside" the space-time would give the same impression of "being" everywhere at once compared to the latter. The expressions are various, but translate the same strange feelings of perceiving time from outside or flying above it:
I had access to both past, present, future and any place in space. (M.Z.)
I had no access to the future, I don't think so, but to the past yes, exactly so, as well as to present since I was seeing myself. It seems to me that I could move around. (P.B.)
I felt I could fly over time. (J-M.M.)
It seems to me that the time is no longer valid. That is, I don't take place within time. There is no longer any past neither future, everything is within the same plane. I got out of the timeline and I can contemplate it AS A WHOLE. But thirty years later, I am still unable to define accurately, using common words, this perceived lack of time ... and both its presence. When you move from one place to another in a flash, when one sees multiple views of the same situation, physically and temporally, that’s not "every day life."
Jourdan: "Have you had the impression of "flying over" time, as one can fly over a landscape, or see it from above?"
Yes, in some ways, move forward or backward at the same time. "Time" no longer appears as fragmented, but as a one and single moment: a "continuum" related to will and free will. (D.S.)
There, the time does not seem to unfold as here. I would say it's "above", a place from where you can "govern" the events and the destinies of the earthly world. Neither was there any space. (A.T.)
I wonder about the word "time". I had the impression of "flying over" a certain portion of time, to fly so quickly but the time seemed at once long and short. That's funny. I felt able to move in time. (F.N.)
When I saw my life, it was like an accelerating videotape, somewhat as if I could fly over it, it goes fast enough to review one's life and yet it lasts forever, I can't explain. (Be.N.)
13. Spatio-temporal Perspective
What could be the predictable consequences of a hypothetical perception from outside our spatio-temporal continuum? Within the framework of this 5D model, everything happens as though NDErs were able to take enough distance to see in perspective not only the immediate vicinity of their body, but also their whole life. Then we could now expect some precise temporal perspective effects.
In our everyday experience, the concepts of time and space are fundamentally different. It is surprising to find several accounts of a uniqueness that has nothing natural nor intuitive for us. Even if he finds it difficult to explain (what we will readily admit), J-Y.C briefly summarizes relativity with some expressions that would have pleased Einstein. Even better, the way he watches his own life as what we could call a "4D spatiotemporal object" is amazing : a 3D form under his eyes, with an "integrated time" which doesn’t unfold, a life he can see from every angle, get more or less closer or change his angle of view, focusing on one part or another… exactly as we do in our everyday life when examining a banal 3D object.
Indeed, at the time I receive this new form of intelligence, I find before me ... my life. I look at this 3D thing that is my life and which does not unfold. The time is integrated in it, it is no more linear. All of one’s life is visible and this "global" intelligence can read it, understand it. (…)
I saw my entire life, in relief, with all the details, people, situations. But in a time that does not unfold, life being seen from every angle with this universal or global understanding. My life was a form under my eyes, which contained everything and that I consulted.
(…) My whole senses were concentrated or condensed in a single understanding concept. The ability to understand and develop ALL, in its wholeness and in its detail. Should I have watched a car, I had known in one thought its mileage, fuel quantity, the wear of spark plugs, how many times it had turned left or right, the condition of all its parts, etc.. It is very difficult to share the encompassing of the three dimensions with the fourth, which merge in a concept that can be easily read when one gets this form of over-intelligence.
(…) Time is no longer linear. Your own life is in 3D and the fourth dimension is fully integrated. At that time, if I had watched a man, I could have known everything about him. His age, height, blood type, his siblings, the amount of all his taxes, his diseases, etc.. etc.. ALL in a single concept.
Jourdan: "Did you feel yourself moving?"
Yes
Jourdan: "When?"
To get closer to my life.
Jourdan: "How did it happen?"
A sort of sliding, zoom displacement.
The only "thing" that I was able to contemplate was my own life. An oblong shape, threedimensional pink-orange hue (always "metallic" as having its own light). I could see inside, seeing-through my entire life course, including time without unfolding time. To see another part of this life I just had to change my angle of view. (J-Y.C.)
This second example is less spectacular, but we find again a "frozen time", a "whole life spread before (the NDEr’s) eyes, its slices being seen instantly":
Totally calm and in a state of unimaginable bliss, I continued to float in a world of breathtaking clarity where the notion of time, that seemed frozen, defies understanding. In tune with this inexplicable timelessness the slices of my life were seen instantly, without any sense of duration. That's quite difficult to explain with "earthly words." My past life did not just appear to me like images following one another in a reverse chronology, as might be suggested by my previous comments. The events unfolded in accordance with the original script, but their succession went backward over the course of my life. Sometimes, and here it's even more difficult to explain, I felt like my whole life was spread before my eyes, undifferentiated in its stages, and still without the sequence of events being linked to time. I know it's crazy, totally incomprehensible, but that's the way it happened. (M.N.)
14. Discussion
NDE are frequently viewed as hallucinatory experiences. Indeed, in spite of numerous confirmed accounts reporting precise details and scenes in the immediate vicinity of unconscious patients, for the time being we have no irrefutable proof about AVPs.
On another hand, the hyperdimensional model I propose allows to understand very simply every seemingly strange perceptions, implying that these experiences could follow definite rules.
So we are faced with several possibilities. The first one is an "inner" hypothesis : NDE are purely subjective experiences, the AVPs being the result of brain activity, this latter having "rebuilt" scenes and details very close to the reality from various elements gathered after the experience. Joseph (1996, 2001) provides evidence which he believes demonstrates it is the hippocampus which is responsible for the hallucinations of floating above the body. As detailed by Joseph (2001):
"The hippocampus contains "place" neurons which are able to encode one's position and movement in space. The hippocampus, therefore, can create a cognitive map of an individuals environment and their movements within it. Presumably it is via the hippocampus that an individual can visualize themselves as if looking at their body from afar, and can remember and thus see themselves engaged in certain actions, as if one were an outside witness (Joseph, 1996). However, under conditions of hyperactivation (such as in response to extreme fear) it appears that the hippocampus may create a visual hallucination of that "cognitive map" such that the individual may "experience" themselves as outside their body, observing all that is occurring. In fact, it has been repeatedly demonstrated that hyperactivation or electrical stimulation of the amygdala-hippocampus-temporal lobe, can cause some individuals to report they have left their bodies and are hovering upon the ceiling staring down. That is, their ego and sense of personal identity appears to split off from their body, such that they may feel as if they are two different people, one watching, the other being observed."
If this hypothesis proves to be the correct one, that would at least lead us to explore the hypothesis of some 5D-like brain organisation, which could present some interest for cognitive neurosciences, neurology, psychology, and all those disciplines which generally seek to explore the nature of consciousness and the functioning of our brain. Like radioactivity at its very beginning, what appears to be only an oddity can conceal major avenues of research.
Another possibility is that of an "outer" hypothesis. Nobody, at present, can clearly define consciousness. We can at the very most safely say that it is part of our world, follows the laws of nature and has been for a long time our only tool to try to puzzle over it. Could it, in some unusual circumstances, show us the first evidences of additional dimensions?
14.1. Four or five dimensions? It is important to clarify some potential confusions if we envisage an extra dimension. We have seen that the first proposals about this subject date back several centuries. At that time, scientists reasoned within an Euclidean space -which comprises only spatial dimensions-, envisaging a fourth spacelike dimension that was a virtual mathematical or geometrical concept. Nowadays, the mathematical setting of relativity is a Minkowski space comprising three spacelike dimensions and a timelike fourth dimension. Then, as our visible universe is a 4D space-time continuum, and considering the multiple accounts reporting spatio-temporal perspective effects, the extra dimension giving an accurate background to the model I have set out would be a fifth one.
14.2. Recent extra-dimensions theories The first proposal of a fifth dimension, in order to unify electromagnetism and gravity, comes from the German mathematician Theodor Kaluza (1921) and the Swedish physicist Oskar Klein (1926). This theory was abandoned, but after a few decades appeared superstrings and strings theories, largely initiated by Peter Freund (1982,1985), who introduced extra dimensions of space in physics and found the mechanisms by which these extra dimensions curl up. These theories involve 10, 11 or up to 26 extra dimensions, which are compactified, curled up at each point of our universe with a finite minuscule size (about the Planck length, i.e 10-33 cm in the K.K. theory). Obviously, this tiny size does not offer a sufficient distance to allow the perspective effects that we have reviewed.
Derived from string theories, which concern essentially particle physics, brane cosmology is based upon brane theories, which attempts to understand the weakness of gravity within our visible universe. In brane theory, a string is a 1-brane, a "membrane" is a 2-brane. In general a p-brane (p is the number of spatial dimensions, therefore a p-brane is in practice a (p+1) space-time) is viewed as a slice inside a (p+1) brane. Thus, according to this theory, our four-dimensional universe is confined in a 3-brane within a 4- brane, a "super"universe endowed with (4+1) dimensions.
Following a first proposal (Antoniadis & al 1998, Arkani-Hamed & al 1998, 2000), Lisa Randall and Raman Sundrum established in 1999 two models of brane cosmology. In the first one (Randall and Sundrum 1999-1), the size of the extra dimension is finite, about 1mm, which is far better than the Planck length but still insufficient.
On the other hand, in the second one (Randall and Sundrum 1999-2) the extra-dimension might be infinite, which is perfectly suitable for the extradimensional modelling that I propose.
Another model, elaborated by Laurent Nottale (Nottale 1993, 2010, Nottale and Timar 2008), is scale relativity. Within it appear two interesting characteristics: a fifth topological dimension and a spatialization of time, which could explain the particularities that we have reviewed about the perception of this latter.
14.3. The Time issue During NDEs, our universe seems to be perceived not only as spatial but indeed as a whole space-time. Several testimonies seem to report some sort of time spatialization, and the main issue is to understand how that could be possible. Saying "our (3+1)D universe is a subset of a (4+1)D universe" implies that we have merely added a spacelike dimension, the time dimension remaining the same. Concerning this particular point, the status of time within extra-dimensional theories is not clear and above all I am not qualified to go further.
At the very most, I could perhaps say that we might understand the particularities described by NDERs such as "no time", "eternal present", "being out of time" by remembering that, according to relativity, an object or particle is subject to time – and therefore has a duration of its own - only if it has a mass, and therefore suppose that "that which perceives" during an NDE is massless.
Be that as it may, I hope one more time that qualified scientists will accept to think about that according to the accounts we have reviewed.
14.4 A predictive modelling? The modelling I propose, like every self-respecting model, must be predictive and lend itself to experimentation. We have seen that, to an observer whose vantage point is situated in a (n+1)D universe, nothing can be hidden within a (n)D universe. Thus a very simple test could be proposed, consisting of a hidden target (for example a colored drawing enclosed in a sealed envelope) put in the vicinity of places where NDEs are likely to occur (ICUs, surgery, etc.). Provided it is unusual and interesting enough, this target could attract the attention of an NDEr, who would be able to describe it after resuscitation.
15. Conclusion
In this short paper, I hope to have given the reader enough information so that he or she can make up his or her own mind about the hyperdimensional interpretation of perceptual particularities in NDEs. The fact that the perspective effects concern time as well as space, and that some patients without any training or education in physics were able to describe with their own words a spatio-temporal continuum seems to me particularly interesting.
To summarize, the particularities that we have reviewed could lead one to suppose that consciousness could be the result of some interactions between 4D and 5D phenomena and/or universes, an hypothesis we cannot simply dismiss and that is considered very seriously by some neuroscientists (Smythies 1994, 2003) and cosmologists (Carr 2008) as well as philosophers (Droulez 2010).
The look we have on a screen, a sketch, a painting or any 2D-like universe allows an instantaneous global information. Waiting for further research and results, the analysis of the perceptual particularities in NDEs in terms of global perception/acquiring of information, a concept that is coherent with our model, should allow us to conduct research calmly and in a purely scientific way. In addition, it should be free from all metaphysical a priori and use concepts which are already within our reach.
Whether the logic revealed by this analysis reflects a particular cerebral function, a new phenomenon or a combination of both, it casts doubt on purely hallucinatory interpretations of these experiences and constitutes an argument in favor of scientific research into NDEs, justifying a multidisciplinary approach gathering physicians, neuroscientists, cognitive scientists, philosophers, psychologists, anthropologists, and now maybe, mathematicians, physicists and cosmologists.
ACKNOWLEDGMENTS: It is a pleasure to thank the editors of the Journal of Cosmology for inviting this paper, hoping that the evidences set out in it will represent some food for thought for its readers. I am grateful to the confidence NDErs graced me with, and for the time they spent answering my numerous and sometimes strange questions. Without them this study would never have seen the light. I am also eager to thank John Smythies and Thomas Droulez for their encouragements and for a careful proofreading of this paper.
