What frightened you as a child? These don't have to be irrational fears.
This thread was inspired by the Childhood Songs thread.
1) The SEGA game Bubsy. There was this noisy piano that rolls down a hill you're running up. It scared me everytime.
2) The Count from Sesame Street (I would have nightmares that he was on TV and I couldn't turn him off)
3) Remote controls for the TV, because my dad would pretend that he was going to turn me off/mute me
4) Shorter-than-average people
5) Taller-than-average people
6) My uncle (after I watched Lion King, I thought my uncle was going to kill my dad)
7) Anybody wearing a mascot costume
8) This game called Dragon's Quest where this blue demon comes out of a drain
9) Anything with glowing eyes
10) The headhunters in a deserted island game
11) Fire, because my mom showed me photographs of kids with third-degree-burns so that I wouldn't play with matches (I still have a phobia of fire but I doubt it's because of those pictures)
12) Lumps in my bedsheets
