There's this old abandoned doctors on the street next to me, so one night I saw out of the living room window there was this grey silhouette of a man stood in the dark outside of it kinda swaying back and forth, I was staring for ages cause I couldn't make out any features on it then all of a sudden it stopped dead still and was facing right towards my direction (like it noticed I was watching) anyway I ran upstairs to get a better look but by the time I looked back out it was gone. I don't believe in ghosts but I have no idea wtf it was it was really creepy
