Out of Body Experiences
So I get into a philosophical debate with someone the other day, and he tells me to explain Out of Body Experiences, and how people who were otherwise dead "come back" and explain things about the hospital room from an aerial point of view i.e. numbers on top of machines or on the floor, etc. I also have a delusional Christian mother who has told me her own little story numerous times of when she was in a hospital floating above and facing her body, but felt a huge hand holding her down from behind.
Is this just a typical modern fairy tale religious people like to cling to, or is there some scientific explanation for these so-called out-of-body experiences? I know dreams are definitely one explanation, but why would everyone have a similar experience? And I'm also sure a lot of the stories I've read are religious propaganda, stories about getting a taste of hell, etc. that try to get 'nonbelievers' to convert.
