What was your most irrational fear as a child?

[StealthMode]

Being buried alive (when would that EVER happen?)

As a kid, I had muscle spasms in my fingers and toes as I fell asleep. After seeing Leprechaun and having the bejeezus scared out of me, I was convinced there was a leprechaun living under my pillow and the tugging feeling was him trying to eat my thumbs when I fell asleep. For weeks, I slept with no pillow or covers so that all my appendages would be where I could see them.
