I don't really know. I don't think I have any REAL fears.. you know, the ones that are supposed to cause anxiety and force you to change your lifestyle..
I have a hate of being touched around the neck, one of my friends nearly choked me in the pool in my backyard (and I exaggerate this- when I was actually getting into the real trouble I just flat out kicked her and got away.) I think that's pretty normal, to have a slight fear of choking. I dunno, but it seems rather like common sense.
It's what I don't have a problem with that I think makes me unique- I have no fear whatsoever of bees and a minimal fear of spiders. Last night there was a spider in my shower, so I picked it up and put it on the stair rail. I don't like it when they're crawling in a frenzy on me, but I didn't really think people liked other things crawling on them. As for bees, well, I can tell the difference between a bee and a wasp, and believe me, I know which one I don't like. You know from the previous paragraph that I have a pool; sometimes I'll walk around the edges of it and save drowning bugs. And I never got why people were afraid of bats. They're cute.
However, I do not like ants. The other day my dad wanted some lemons for apricot jam (mmmm :9 ) so I went out and grabbed a lemon. Turns out that lemon had ants swarming all over it. I freaked, threw down the lemon, wiped my hand on my shirt numerous times and went inside and scrubbed my hands very, very clean.
I guess things have to even out in the end, and my bigger fear is that I fail in life and am forced to work at macdonalds at minimum wage.
Also, you have absolutly no right whatsoever to question someone as to why they are afraid of something. It's not something where you go, "Hey, I think I'm going to be scared of horses now!" or "You know what? I love horses now, I'm not scared of them."
/EDIT: Oh, and I'm scared of giving birth to a child with a mental defect. I HATE dealing with small children. What would I do if my child was stuck in a state of childhood? It would ruin my marriage, ruin the rest of my life, my family wouldn't support me, and I don't know WHAT I would do. (And yes, I do have a fairly good reason for being so worried. But that's personal stuff that isn't for the internet. <3 )
