It's the only threshold many humans would never willingly cross. Death carries a finality that nearly all other human experiences could not bear to carry. Our only hope before hopping on that one-time ride is to make sure we've done as much as we can in our lives before the final threshold is before us.
But, not everyone greets death once, as evidenced by these answers to Reddit user, r/wookieoncrack, who asked:
[Serious] Redditors who have been clinically dead and then revived/resuscitated: What did dying feel like? Did you see anything whilst passed on?
My heart stopped in a hospital. It was rather unexpected. I was watching the monitor hit 41 bpm then 0 and all the lines were flat. I had just enough time to say "huh?" before losing consciousness.
I had a dream that was very short and more disconnected than most dreams. I say confusing but others may say profound. The content was more or less about what was on my mind at the time and some of my interests. Mostly very familiar stuff. There is nothing after really. I can see how people could see their life flash before their eyes or see god if that is what was important to them.
Drowned at a public pool when I was 7, woke up a week later @ children's hospital.
Apparently the first word out of my mouth was hamburger. I don't remember anything on how it happened. Sometimes I think I may still be dreaming and never know. Also had to go through some walking therapy, laying in bed for 7 days straight does a number on your muscles.
I was really young at the time, I believe six. I didn't see anything but I woke up really confused why I was in a hospital and surrounded by a lot of my family. It honestly felt like I was just sleeping normally I guess. Felt well rested though, which was nice.
I didn't know I had died until I was told and an officer preformed CPR on me for about 15 minutes until I was revived by the doctors. Fantastic man and I wish I remembered meeting him.
