Drowning (the ocean mainly at night) wich is wierd because I dive.
normally there is no problemes, but right as dusk sets the water takes on a sureal look like oil on top. And I look around , the waves brakeing behind me on the rocks, and relize I've go to make it back thru in the dark again.
I would have to say that is the only reacuring fear I have, strangely it attracts me.
