tiny holes in things, like sponges but for some reason i dnt mind sponges but anyhting else with little holes in realy freaks me out!! strange I know!!
I hate when people feel the need to jingle their change in their pockets. THE SOUND of it irritates me as much as scratching nails across a chalkboard, or scraping yer knife and fork on a plate. Ear abuse that is!
walking down City Road, Cardiff and being leered at by men. Particularly if it's getting dark, that seems to bring them out en mass. And you don't even have to be wearing anything particularly revealing either, just being female will suffice. /rant
Masks - I get really on edge if I can't see someone's face.
Those little insects in bathrooms - silverfish? I hate them.
Other people's hair left in the bath/sink/shower etc. I have to rinse every surface, just in case there's a small one left. I physically shudder to see them.
Oh, and frogs. I picked one up once thinking it was a rock. I'm now terrified of them.
I'm sure there's more; I seem to go through my life getting creeped out by different things!
