When I was about 8 years old, I had this Barney Bedtime Book and it was around Christmas Time. They kept playing "Santa Claus Is Coming To Town". Well, the lyrics creeped me out and I thought Santa meant to burn my eyes out with the Sandman(the Barney book had a story about him). So I laid there in bed, on Christmas Eve shaking in fear.
(I have another one!)
I once, about 7, believed that the Tooth Fairy would yank all my teeth out. I always woke up in the middle of the night to make sure my mouth was shut.
