Clowns.
Spiders.
Most physical deformities.
Dwarves.
Dried toothpaste.
Those cotton wool buds on sticks (I believe the yanks call them q-tips).
You think I'm joking, but I'm genuinely scared of all of the above.
Can work through my fear on the latter three. Can speak to a dwarf, can clean up crusty toothpaste, and can use cotton buds - but I feel lightheaded/sick and get a proper sweat on when I do.
Will likely get violent if you try coming near me with one of the top three though.
I know they're stupid fears, you don't need to tell me.
But that's what makes it a phobia, isn't it...
