My fears are a bit tame insofar as I don't know if I have any that make me reel in disgust/terror all the time.
I can stand looking at spiders - I even tried to hold a one-sided conversation with one before (if you ever worked the grave shift at a store, you'd understand). And if I see one on the wall, I can look at it just fine. Don't mind them running around the walls. But if I see one in the shower or sink, I'll turn on the water and flush it down the drain. If I try to be nice and lure one up on a paper or into a bowl so I can release it outside, if it gets out of the bowl or climbs too far up the paper toward me, I'll spaz out.
I'm worse with moths. I won't even try to save a moth or talk to one. I hate moths, but not really terrified. But they're so big, I generally try to shoo them away - and spaz out when they fly close to my face.
I used to be terrified of ghosts (saw Ghostbusters when I was 5, I think that was the source of my fears). Nowadays I get jumpy at shadows and I hate the dark because of my fear of ghosts as a child, but for the most part I'm over it now.
Decapitation has always been a big no-no for me, though. From horror movies to shows like Gam eOf Thrones, to shit like Faces Of Death, and even in anime or just paintings of it - both human and animal alike - I cannot stand decapitations. I can force myself to look at them, but I wouldn't be surprised if I have uncontrollable nervous twitches when I do. If something had a head, it should continue having a head indefinitely. In real life (as opposed to in film), I can't stand viscera either. I won't even look at roadkill.
I might have a minor fear of [human] corpses. I mean, other than my grandpa's and possibly my mom's cousin's, I don't think I've even looked into coffins. Might have stemmed from when I was watching a parade sitting in front of the funeral home and I had to take a piss, so I went into the funeral home looking for the restroom and walked into an "occupied" viewing room accidentally. But if i see them on TV or whatever, I don't mind.
Biggest fear is my cat getting outside (sans kitty carrier/tote). My cat's an indoor cat because I don't trust the outside world with her.
