I don't like heights because I always feel this urge to just jump off and see what happens, which isn't a good thing when you are standing on the balcony of a 10 story building (No, I am not suicidal)
I don't like not being able to see the bottom of places I'm swimming in. For this reason I like pools, but I had the limited space in a pool and would way rather place in a lake or tube down a river, but they tend to be more dangerous and that scares me.
I have fears of never getting married and being one of those woman that eats T.V. dinners every night in front of the T.V. watching reruns of the brady bunch, and my best friends are my 37 cats, and my personal hygiene goes out the door. This definitely gives me nightmares.
Sometimes being alone scares me. I love watching my aunts house while they are on vacation but I also love that her dog and cat are there to keep me company and hopefully protect me or warn me of danger.
Yah, I think those are my only real fears. Kind of the standard ones.
