This isn't a belief, but an amusing old irrational fear... when I was around 5-6 years old, I was TERRIFIED of the music that would play in the castle levels of Super Mario Bros. (1-4, 2-4, etc.) The bass would make the speakers on my TV vibrate. I used to get all the way up to Level 8-3 using warp zones, then reset the game and play over again. I got so upset when a guest at my house didn't use a warp zone that I ran into my room, cried hysterically, and vomited.
