Spiders, ugh. I get these massive Huntsman spiders that come crawling into my room or peeking into my shower. Also have to watch out for funnel webs and red backs although they've never been too much of a problem. I've just glad I don't have to worry about giant, bird eating Golden Orb Weavers like that one in North Queensland. (If I lived near near there, I'd have moved. Seriously)
I also have a fear (although I reckon it's more of a prominent aversion) of other peoples saliva. Naturally, my friends harass me over this and use it to control me. One also tricks me into swallowing it (like on food) and stuff. (she's trying to 'cure' me) Makes me a bit upset but she doesn't care that it makes me feel violated. (see? It didn't kill you!) I know it won't kill me, my God. (although if it does I'm taking her with me)
I also fear death. Fears generally link back to this one even though I know a Huntsman won't kill me. Sometimes I'll be walking along and just get this terrible dread even though nothing bad happens because I remember how suddenly people die and I'm scared it'll just come out of nowhere and I know someday it will. By no means does this happen often though.
Oh and then there's public speaking... Depends how casual it is though, who's watching, how confident I feel.
