Sounds like an interesting movie. When I was near death (sepsis, in a coma on a ventilator with my heart stopped beating several times and the doctors wanting to pull the plug saying I would be a vegetable because of lack of oxygen to my brain) I remembered nothing of the experience. So count me skeptical but would love for these experiences to be true.
I’ve heard both - one guy died and told a friend that he’d go back in a heartbeat - that heaven is wonderful and that my friend has nothing to worry about. Another guy’s heart was stopped for too long...somehow they brought him back but he has no memory of anything.
