experiences may be mystical, out of body or near death or in normal condition experiences. Our culture traditions religions believes in spirit, soul, super soul, & evil soul that could leave the body & is immortal undestreyable & permanent.
Science & certain religions has no place of soul theory. Ideas of soul have no measurable consequeness, no testable predictions. There can't be another body that is vehicle of conscienceness. If something really leaves the body in out of body experience then you expect it to be able to see at a distance. What relationship there is between this world & the other one? I other world is an extention of physical, then it is ought to be observable & measurable. The ideas are complete empty even though they may sound appealing.
Of course we can never prove that astral bodies don't exist but may guess, it don't Another theory of dying experience is analogous with being born. Cent of body experience is reliving the moment when you emerged from your mother's body, tunnel is birth.canal & white light is light of world into which you were born. The birth canal is stretched & compressed & baby is usually forced through it with the top of his head. Also it does not have the mental skills to recognise the people around this capacity changes during growing up.
According to this theory people who were born by caesarians section should not have such experience but people who were born by caesarian also have same experience of tunnel. So it is not one's own birth that is relived. This reduces the Theory to complete vacuousness.
Imagination or hallucination if are not our own experience then why these kind of hallucination? Why tunnels? Some say tunnel is a symbolic representation of gateway to another world? Tunnels do not only occur near death They are also experienced in epilepsy, migraine when falling asleep, meditating, or just relaxing with pressure on both eyeballs, with certain drugs. It is as though the whole world becomes a rushing roaring tunnel & you are flying along it towards a bright light at the end. Brain activity is normally kept stable by some cells inhibiting others slow dough. Disinhibition produces too much activity in the brain because of lack of oxygen or drugs (LSD) which interfere with inhibition.
Cowan uses an analogy with fluid mechanics to argue that disinhibition with induce stripes of activity that move across cortex using mapping it can easily shown stripes in the cortex would appear like concentric rings or spirals in the visual world. In other words if you have stripes in cortex you will seem to see a tunnel like pattern of spirals or rings. Theory shows how the structure of the brain could produce the same
