It is a big puzzle why near death experiencers stated that their experiences are "definitely real, more real than our physical reality and mundane world", but at the same time they provided far far less information amount than our physical reality. I don't understand this, because they seem to have no reason to lie.
Basically, one hypothesis that I have is that are viewing reality from a higher dimension which intuitively would contain more information. Raymond Moody has attempted to study nonsense in order to unpack rational clues to the nature of the world after bodily death. I am pretty sure he is writing a new book based upon his research on nonsense which includes a comparison sample of NDEs both before and after being taught a method of categorizing nonsense.
The point is to figure out what kind of nonsense this information is -- what category it belongs too. I find this brilliant but other's do not and why they don't remains a mystery to me. Perhaps because it reminds them that on the empirical evidence alone one cannot believe in an afterlife. It requires a rational leap since we do not understand consciousness.
My guess is that many scientists in NDE studies want to believe rather than want to know. But that is ok. The world is a harsh place sometimes.
