I was reading some survey data the other day on the subjective experiences of people who have been through Near Death Experiences, and 15% of people interviewed had some kind of a concious experience while they were clinically dead. 9% included the classic out of body experience and 8% even reported encountering spiritual beings. Also, individuals who have had a NDE tend to experience an increase in religiosity.
My question for you is how do we explain this through the lens of materialism? I am aware that subjects under the influence of drugs like ketamine or PCP have reported similar experiences, and that most of the theories about the "calm feeling washing over me" and "a tunnel of bright light" can be explained by blood loss or interferance with the functioning of the frontal lobe.
However, what I'm interested in, is the ability of NDE subjects to relay information about the surgery that took place while they were unconcious (or even dead) and report the sensation of leaving their bodies to survey themselves undergoing surgery.
