I actually don't fear a whole lot. But, there are two things that get under my skin - Tarantulas, and roaches. I can handle the former before the latter, although both count as some serious nightmare fuel. And while I'm not quite sure what it is about tarantulas that creep me out, they just do.

Roaches ... Might have bee the horror movie I watched as a kid. Bleh. *Shudders.*
