You Are Jaws
You're scared of what you can't see right in front of you. Your imagination tends to get the better of you.
And for you, something like the deep, dark ocean is obviously pretty terrifying. Who knows what's lurking right next to you?
The idea of trying to get away from something that's after you really gets your heart pumping. Being chased horrifies you.
You're also quite scared of big, hungry animals with no sense of right or wrong. You know a shark will stop at nothing to make you its lunch.
