What is the most terrifying situation you have experienced in your life?

Mine is more what my mind can do because I get psychosis. The fear is getting stuck like it. One time I could feel a massive hole in my head, I couldn't remember things I ought to remember like date of birth, I believed I was dead and every time I shut my eyes I could see the beginning and end of the universe, ears rushing. It was awful. When I realised I couldn't be dead or maybe I was in hell I got very paranoid. My brain has played some other horrible tricks on me.

I've been tied up. Had petrol put on me and threatened to be put on fire. Had a gun to my head. Raped. Locked myself in toilet crying to try to hide from stuff as a child. But still what my own brain did and could do again is scarier.
