When I was a kid, I was so scared of vomiting that when it happened I'd run through the house to get away from it, with the result that every room would be sprayed with puke. As you can imagine, my parents were not amused.
Thunder and lightning don't bother me, if I'm outside. If I'm inside when a thunder storm starts, I won't feel safe until I'm out of the house.
Sometimes I get panicky about germs, but it's not constant. When it's bad I'll wash myself till my hands bleed, but for the most part I'm on top of that phobia now.
I'm extremely scared of crowded spaces, enclosed spaces. Although I've managed to travel on the underground in London, it's only been in such emergencies that I had no other option, and I was still sweating and shaking with fear several hours later... According to my son who has been with me on a few of these trips I just stand there with my eyes closed moaning.
I'm definitely scared of meeting new people, though it rarely show.
Arachnophobia... definitely, though I know it's a silly thing.
I absolutely HATE having anyone come up behind me. I always want to have my back to a wall if possible. I can't eat in a restaurant if I don't have my back to a wall, I can't read in a libary unless I'm near a wall.
I hate talking on the telephone.
There's probably more, but those are the ones that come to mind.
Oh... fear of Christmas. Not so much the day, but just all the jazz around it. Connected to which, fear of supermarkets and sales. I keep expecting someone to kill someone in the materialistic frenzy.
Sometimes I'm too scared to go into Tescos, or Asda... there's just too much stuff there, and too much to choose from.
