My biggest and dumbest fear is zombies, D&D magic zombies as well plague versions. But, any smart, talking version doesn't count. I evaluate new places for points of entry and possible escape. I check my partner when I go to bed to make sure he's still warm and breathing. It is super childish and utterly ridiculous.
I will still watch some zombie stuff but not too close to bed time. I'm a mild to moderate horror fan and I'm way too into all vampire things except twilight. Although very dumb vampires are similar to zombies, they still act more like animals and don't trigger the same fear.
