I have a lot of terrifying moments myself, most of which were dreams that came true and some physical happenings.
As child then I always saw terrible accident scenes in my sleep, when I wake up, two or three days later these accidents actually happens. I was too scared to let anyone know about this because I felt they would see me as evil but I wasn't evil I just happen to have really scary dreams that happen real life.
One day in my sleep, I dreamt and saw myself being chased by some people without faces, I was too scared I just kept running for my life but it was as if my steps were ordered towards a direct by the chase and when I finally got tired of running, as I stopped I found myself in front of a graveyard and was told " that is yours, go in" immediately I woke up sweating profusely, I couldn't even speak out of soo much fear, I was just staring at the wall. But that wasn't even the scariest for me lol
