As a very small kid, at 4 or 5, my great-grandmother scared me, I kinda remember she coming to speak to me, and she was very old and spoke spanish, and I remember crying and running away, behind a sofa and everyone laughing. Than, I remember I was scared of Judge Doom from "Who Framed Roger Rabbit", I remember watching it at the theater and (oh, by the way, SPOILERS) when judge doom gets skwatched and flatened I was horrified but kept looking, and when his eyes come out and he looks up with his red eyes and skeeky voice, I lost it, I just covered my eyes for the rest of the film. To this day, I blame Cristopher Lloyd and Robert Zemeckis for my insanity... I can't remember anything else that really scared me as a kid.
