What's a silly thing you used to be afraid of as a young child?

I remember thinking that if I ate a black watermelon seed, a watermelon plant would grow inside me. I remember my mom saying something like “I don’t think your stomach is the best growing conditions for a plant.” lol

I also remember this metal letter-holder my dad had in the shape of a dog used to scare me. I think it was the eyes.

My brother used to be afraid of fire in movies/cartoons.
