I hate spiders, and insects. Scare the crap out of me. They're so gross. Thank god I dont live near the equator. Bugs and spiders down there are 20x bigger, and thats where all the real poisonous ones are.
I'm not too good with heights and speaking in front of a crowd of people I don't know, not a fear of them though, just something I don't like.
There are some things that scare me at first, but it won't scare me anymore a few seconds after (for example a mouse that suddenly runs towards you, it would scare the crap out of me, but once i know it is a mouse, i won't be scared anymore). So basically there is nothing (within my experience) that i am scared of, and if i find it scary, i'll just overcome it. i have a slight fear of heights, yet i love to fly, i love to climb a wall, i love to climb a rope, i love to bunjee jump, so the fear of heights doesn't bother me, i'll just ignore it.
