Do you have any type of phobia?Watch
I did a scuba diving course and in the deep end of the pool I had a massive panic attack and thought I was going to die. I felt so trapped with no way out just completely surrounded by water. It was awful. Needless to say, I didn't finish the course.
Also, people in clown makeup freaks me out.
Also possibly the open ocean, but that's not been tested :P the idea of being IN the open ocean, as in swimming in it - that makes me feel anxious. I think it's the sense of being totally and utterly exposed to anything that could come at you from below, with no way of getting away from whatever it is
Although I do come close to phobia levels at the thought of being surrounded by vomit, blood or excreta.
Not keen on being near hospitals or sewage processing/disposal facilities.
