I'm the same way with screamers, probably the exact opposite with gore though.
Last summer, I happened to fall for a fake screamer Facebook page that was a promotion for a flash game called The House 2. I happened to fall for like three screamers after that too. The next morning, I felt okay when I woke up, but then I got on Gaia and listened to some song called 'Hamburger Lady' by Throbbing Gristle, and even though it was a song I would usually adore, for some reason I was terrified of it, and for the next three days nonstop, I was feeling the worst fear of my life. I couldn't even look through my sketchbook (I like to draw surreal horror), my Tumblr page, or into any mirrors. To this day I don't know what caused that overload.
