NDEs... Why would it only be possible to hallucinate when you're *not* dying?

Some people who have had an NDE can report with exact accuracy what was going on inside the room while they were dead . ie. who was there, what procedure was done, what was said, etc,. Others have reported what exactly was happening in other rooms of the hospital while they were 'dead '. Like who was in the waiting room, which family members where there, what the Dr. told the family, what the people were wearing etc,. How can this be done in a hallucination? This would suggest that the mind , consciousness can leave the body and gather information from the world around it, come back and remember and report it with accuracy, to the astonishment of the Drs. and nurses and other people that came and went from the room during code blue, flatline, dead.So death or near death hallucinations maybe part of the complex visions experienced, but there are some unexplainable events that would be impossible to describe if the person had not actually seen it, been inside the room and come back to explain what they had witnessed in exact detail. There is more to it than random last gasp chemicals of the brain making up stories for why:? Why would a body use that energy , to create a hallucination , for what reason? You would think the body fighting to come back from near death would be using it's energies into revitalizing important systems like the heart beat, respiration's, restoring functions as blood pressure and pulse rate, etc,. Saving the brain cells for use to be alive again.

It isn't possible under only those circumstances. Anytime you deprive the brain of oxygen, you can get these experiences.

As for remote viewing, the government spent millions on the program with no statistically significant results. If there was something real there, the effect should be way more significant than chance.
