For me, the great white shark is my worst fear. I have no idea why, as I live in Oklahoma and have never even seen one in real life. Yet I absolutely fear them (but at the same time I'm very fascinated by them). I have at least one shark related nightmare every week since I can remember. What's your worst fear?
