1. Clowns
2. Dolls/Mannequins
3. Some faces eg. in photos etc. (particularly the ones that seem to be staring at me)
4. Dead things
At uni I live near Wollaton hall in Nottingham, first time I went I figured the rooms would be set out like they used to be years ago but no - pretty much filled to the brim with taxidermy animals (look at fear 2 and 4), and I could skirt around the edges of the room of anything, they were literally everywhere :'(.
And the last one is kinda hard to explain but here goes....
5. Swimming over things makes me feel extremely sick whether its just a bobble or patio furniture (people thought it was funny to throw it in once when I was on holiday). And this applies to any body of water, from swimming pools to the ocean.
The only explanation I can find for it is a story in the news when I was little about a little girl drowning because pond weeds wrapped around her ankle so people were unable to rescue her.
