Clowns have always creeped me out too ... not fear level, but just a general creepiness

My fear is being held underwater. I've almost drowned a couple of times - once when i was really small in swimming lessons and fell off a flutterboard in the deep end and had to be pulled out and resusitated on the deck; second when -again- in swimming lessons, the kid next to me freaked out while learning to tread water and dragged me under. So, i just am petrified to have my head held underwater - i can swim at the cottage (with my floatie cushion, etc.), and not being able to touch the sides or see the bottom doesn't bug me. Just having my head held underwater does it. I had an ex-bf who decided (even after i told him about this) that it would be fun to jump off the dock beside me and pull me in with him - i think i almost killed us both!
