All I can offer is anecdotal but a certainty that I shot out of my body so completely that I didn’t even have a memory of how it felt to be in one. Didn’t see a light or meet anyone but the profound feeling of ‘being in the right place’ is unforgettable. There was also no concept of time, literally no concept and no time. As I re-entered my body I re-encountered all the concepts of time and the physical world The inexplicable part was that the person I was with at the time knew I had left my body and could describe where I was and what was happening.
I have examined it for hypnotic suggestion but that’s not the answer. We had not eaten or drunk anything, or tried to create it. Unfortunately, that person is no longer with us to explain how they were able to share the experience. There is a difference between dreams you have to consciously recall and electromagnetic events that are so vivid they become part of you.
