Although i don't have any legitimate shit-myself-on-sight phobias, i'm scared of heights, spiders (almost phobic of these chaps, i freak the fuck out upon physical contact) and stinging/biting/unknown insects (i'm not afraid of house flies, for example). I don't know how i got any of those fears, though.
Slightly more unusual fears include fear of getting crushed, fear of "nightmare faces" (more so than would be considered normal) and, curiously enough, fear of faces that are screaming in terror. Perhaps that last one is just my mirror neurons flipping the fuck out. :U
