A childhood belief about vampires

I didn't believe in Santa, but I knew that vampires were 100% real.

I thought that as long as the cotton sheet covered all of my neck, it would protect me as sure as steel. I worked it out along with that whole invitation mythology. A vampire couldn't come into your house unless you invited them. Well, I figured that my sisters were pretty thick-headed and might unwittingly invite Dracula in without knowing it, but as long as my neck was covered, I was UN-inviting him to bite me.

I also told my little sister, after watching Salem's Lot on TV, that if she was ever turned into a vamp, I would NOT open the window and let her in.

I think that little speech gave her nightmares for weeks.
