Zombie apocalypse or aliens dominating earth. That's my worst nightmare ever. I dont like smashing dead people until they're, well, dead. It just feels wrong. Though I love watching brutal scenes. Also, I hate the thought of aliens ruling over the earth, i mean, they came from outer space and we dont even know how or what they think, so it's a pretty bad situation. Oh! And ww3. Please don't. I wont be able to survive because my survival skills and knowledge doesnt even exist. Let's just all agree to the idea of world peace.
