Fear of people's bodies with animal heads.

I'm 24 and for years now have been absalutley petrified of people's bodies with animal heads.

It's a really wierd one to explain but they can sometimes appear in films (300, etc) Also, at the moment the window display for River Island (in England) is the manekin's bodies but with goat heads or other animal heads. I could honestly cry.
And if i see someone wearing an animal mask - for instance a rubber pig mask, I would literally run miles screaming.

I don't have a clue what this fear is called but if anyone could tell me I'd be so greatfull!
Everyone thinks I'm mad for being scared of it but it's so bad!
