INTROSPECTION - are zombies achievable? Is creating zombies possible?

The topic of zombies seems to be taken into account by games and movies lately, showcasing postapocalyptic worlds. Predictive Programming, obviously, getting the majority used to the idea of what some folks' fantasy of the world would be. Sure it can sound awkward to believe, but keeping people ignorant is already keeping them dead. And walking dead around the streets? Well, either zombies, or people stuck with their noses in their phones soudns kind of the same thing to me XD
