I Have An Unnatural Fear of Garden Slugs

I don't quite know what it is, whether it's the look of them, size, shape, texture or what. They terrify me, I can't help it, every time I see one I crumple, I can't help it, I just go limp. It's almost like fainting but I stay conscious through the whole thing, I just can move very well. It's damn scary because it's like a turn into one of them! Hyperventilate, scream, shout, shake, sweat it's uncontrollable and I don't know why either. People think it's weird and it is, but I still can't stop it
