Birds also weird me out but not I'm not really afraid of them unless they are swooping down on me.
I also have a fear of not being able to see. If I'm somewhere really dark I tend to freeze up in fear. I hate not being able to see.
OT fact: Birds are the most aggressive creatures on earth in relation to body size. IMO, it's just their inner dino coming out

Oooh, not being able to see... I have that too, but mine is always when I can't hear anything either.
Of course, I think I just got one to top them all off: Monster under the bed. I'm 17, but still. I hear bump from under my bed a practically crap myself. I even go so far as to cover my head with my pillow sometimes, it's that pathetic...
Also, zombies. Seriously, who thought those up? I wanna feed them to a zombie, just so they can see what nightmares they dreamt up... -shivers and looks over shoulder- I can't play zombie games, watch zombie movies, or even read real zombie books. Not even "Night of the Living Trekkies", which is pathetic. And that's (Trekkies) actually a word in my dictionary, lol.
