When I was little, I read Scary Stories to Tell in the Dark. I read the Ghost in the Mirror myth. I used to think that if I saw a mirror in the dark, I would see a ghost and that the ghost might try to kill me. To this day, whenever I have the chance, I cover-up a mirror or turn it around before I go to sleep.
