It's hard to claim that a near-death experience is "all in the mind" when the experiencer can relate details of what they saw and heard while they were clinically dead. Jan Holden explains the importance of the book The Self Does Not Die, which contains over 100 reliable, firsthand accounts of perceptions during NDEs that were later verified as accurate by independent sources.

At 5.00 mins, Tricia Barker gives an example. While "dead" she was able to see her stepfather eating a candy bar in another room and her young daughter standing on a table. She recounts how she was told to return to her body and become a teacher. As a result, she has been able to share knowledge of the afterlife with her many students.

At 18 mins.45, Stephanie Arnold shares a most interesting set of experiences. During her pregnancy she had a strong and detailed premonition that she would have complications in childbirth and that she would die. She was only saved because one of the many doctors she had warned had taken extra precautions. Arnold was able to access detailed memories of what happened to her during the time she was dead through an hypnotic regression. These memories were later verified by the medical staff who had been present.
