One Reddit user said after losing a lot of blood during surgery, he was medically dead for “several minutes”.
Monitormonkey posted: “I woke up in what looked like space but there weren’t any stars or light. I wasn’t floating so to speak, I was just there.
“I wasn’t hot or cold, hungry or tired – just a peaceful neutral kind of thing. I knew there was light and love somewhere nearby but I had no urge or need to go to it right away.
“I remember thinking over my life, but it wasn’t like a montage. More like I was idly flipping through a book and snippets stood out here and there.
“Whatever it was, it changed my thoughts on a few things. I am still afraid to die but I’m not worried about what happens after that.”
“I was being sucked into a black hole”
