Deep water. If I can't see the bottom then I'd really rather not have anything to do with it. After all, there could be anything down there.
Also, spiders. Specifically, touching them. If there's one on the wall then I'll just be very, very, very aware of it's presence but generally fine. However if I look down and see one crawling up my shirt... yeech. I get deadly calm until I've gotten it right the fuck off. Then I quietly freak out.
This one time when I was thirteen I woke up with on my face. Bear in mind that I live in Australia. Not fun.
