Unless you're a psycho, there's no such thing as a vampire and there's no such thing as a werewolf. But there certainly are people who could be controlled by a drug like Scopolamine, to lose all will and do your bidding. That's what the whole voodoo zombie thing was about, with chemical mind control, so it is possible to have real zombies. Maybe the [doomsday] preppers weren't so wrong. I thought they were idiots. How can you prepare for a zombie apocalypse?
