I used to believe that there was a little troll with a jingle bell on his hat that lived in the walls of my bedroom. I thought he had little doors all over my room, and when I turned my lights off at night it would climb up my headboard and kill me. As you can imagine, I never went to sleep without 1 or 2 nightlights on.
But if I heard what sounded like a jingle bell, I would scream and hide under my covers till morning. Boy, was I stupid!
