I think I heard the recovery time for a soul is around 45 minutes. Don't quote me on that cuz I'm not sure where I heard that from.
Depends on what you call a soul haha if you think a soul is basically your personality sometimes dying temporarily gives you brain damage in spots that affect your personality. There was a case where a child of age 6 or 7 drowned and was clinically dead for 4 minutes came back a sociopath, no joke.
no... I don't think you ever lose your soul. It's your essence. You can lose your body. Did you have a near death experience?
of course. haven't you noticed how all those near-death experience people end up eating brains for the rest of their life?
