Is it possible, because we are all wired in the brain the same basic way, that a brain, starved of oxygen and losing brain cells, in a total systematic way, shuts down enough functions that a vivid dream-like state is induced that all the NDE have in common? In other words, could the NDE be simply a matter of the brain's last moments showing our consciousness breaking down? I have read about people who deprived of all sensorary experience in experiments having visions, feeling people or things touching them, voices heard, etc.
Anyway, it would be nice to have my hypothesis above disproved.
