A childhood belief about ghosts

I can't look at the mirror in the dark, even at 14 i can't. But it's not because of the following:
I remember the Bloody Mary thing. Ya know I researched that and found a whole bunch of info on it and even though I knew it couldnt be true I've always been creeped out. I tried chanting Bloody Mary according to the ditrections, but I always panicked and left the bathroom, somehow I always thought that the room was red and the door would be locked..from the outside.Creepy.
