Since I can remember I've always been afraid of:
-Spiders and Centipedes!! (really anything with more than 4 legs, the more legs the more afraid I am of them)
-Goats -- I was attacked by one of my grandma's goats as a young kid and to this day I won't go near one.
-Walking upstairs from the basement -- like another poster said, I can go downstairs, be fine, but when it comes to comming back up I run up afraid something's behind me
-Needles -- hate hate hate needles, injections I can deal with but taking blood is horrible to me, I avoid it like the plague.
