Veins. Neck veins disgust me, when someone gets mad and starts screaming and you can see their neck veins pop out and Gwen's new video Hand veins and muscle veins too.
I'm terrified of
inanimate objects that come to life (I guess more aimed towards film fears)
the ocean
butterflies (really anything that flies, I hate birds and insects too )
mannequins and dolls
I'm still terrified of the dark but that stems from my fear of the unknown, just like my fear of the ocean. I don't like what I can't see.
