Well I'm dead afraid of dark,up to the point I can't move anymore and I start crying and panicking...
I'm also afraid of body interiors,organs,eyeballs,etc...Curiously,blood doesn't affect me at all.It's not really a phobia,but more of a pathological disgust.Assisting at a churgery would knock me unconcious.
I'm really afraid of the Flood Infection forms from Halo,the Facehuggers from Alien and the Headcrabs from Half-Life.I'm always scared one of them will attack me from the back at all time,but I know it's a silly fear induced by playing too much video games
...
I'm very afraid of heights,and simply [thinking] about heights,or a freefalling sensation,makes me feel very uncomfortable and can sometime cause me to panic...
I'm also dead afraid of a lot of other things,but oddly I can't seem to remind all of them...
