This isn't too weird, but DROWNING. I hate hate hate going down below deck on a boat. Smaller boats (like small sailboats, with only one room) are almost okay. I just have this fear that the boat will take on water, and I'll be trapped below. I can't watch fake drowning in movies. I will just sit and shut my eyes or leave the room. Or on Fear Factor when they have to swim through/under things in the water. I couldn't. I'm afraid I'd be trapped. I could never ever go on a cruise. I can't get too near the dock if I'm swimming in a lake, because I'm afraid I'd get trapped under the dock.
For some reason I'm totally okay in swimming pools or the ocean, or far away from anything I could get trapped under.
