Interesting questions ...

What is it that gives you the heebies? Snakes and spiders are probably the two that most consistently give me shivers. Oh, yeah, gore in movies is not a favorite either.

What is it that you fear? Heights (which is funny because they didn't bother me as a kid) and drowning (and I don't know why)

What is it that terrifies you beyond all reason? Can't think of anything ... but I'll probably know when I find it.
