This thread gives me the chills...
I can't say I believe in them but I don't deny their existence.
When I was 10 I awakened to the image of what appeared to be the grim reaper standing next to my bed. He wore a dark, full length hooded robe. For some reason his face was pitch black. I couldn't see his face. He wasn't facing me but definitely looking towards my direction like off to the left a bit. I was so scared I couldn't speak or get up. I couldn't move a muscle. I will probably never forget it.
