I'm afraid of the ocean. When I go swimming there, if my feet can't touch the bottom, I freak out. I won't put even a toe in the water at night. No telling what kind of things there are lurking, for all we know there's some enormous foot eating squid that comes from the depths at night looking for a nice foot to eat (Exaggerating, but still)
I'm deathly afraid of loose mice. Not pet mice that get loose, but wild ones that just pop out of NO WHERE. I scream, squeal, hop on furniture, flail madly while whining, etc.
I'm claustrophobic at an insane level. Me and my friends used to hang out in this giant tunnel, we'd sit there and talk, listen to music, etc, I could never sit on the inside, I had to be on the end or I hyperventilated.
I'm scared of swimming in ponds and lakes as well. Wont' set foot in them unless I'm on a boat, even then I flip out. (Had an experience one summer while I was dozing off in an innertube and a fish kept rubbing up against my butt, I swore that thing was trying to eat me and STILL believe it was).
I'm deathly scared of spiders and cockroaches. I don't see how some people can have tarantulas. About the time that thing got loose and wound up on my face in my sleep (Which it would, my luck SUCKS like that) I'd pee myself.
My biggest weakness is zombies...Oh my...I hate staying in a house with a lot of windows because in the back of my mind, as stupid as it sounds, I'm thinking "Holy crap if the zombies come, we're in trouble."
I'm also scared of big crowds because I do not like people I don't know touching me an that's usually what happens.
