I'm afraid of dark water...
I get creeped out by going in pools or the ocean if the water is dark. If its night and I am under the water in a pool and i can't see clearly to the other side I freak out. Same thing happens with deep ocean water. The wierdest part is if I look at a cola bottle and imagine being stranded in an ocean made of nothing but dark black cola it freaks me out a little too...now I know thats wierd, but does anyone get fears about water?
