What is the most horrific thing you've experienced in life?

A stroke that should have killed me suddenly. While being in the worst shape of my life, on the ground with severe vertigo, projectile vomiting, and in the worst physical pain I'd ever been in, the horror really started when I closed my eyes to die and some how woke up...

I had no idea about life saving medicine or what happens when you're close to death and it's their job to save your life on a different kind of time where they tell you what is going to be done to you... It's really a treat being told that you're getting a spinal tap in the same 5 minute window that you get the spinal tap...
