Recently the Centers for Disease Control used the prospect of a zombie attack to encourage Americans to think more about disaster preparedness. It was an interesting learning tool, using a premise seemingly silly and farcical but, as anyone who’s ever watched a zombie horror movie knows, nonetheless potentially dangerous. The idea of the dead coming after the living has always been the stuff of nightmares.
It also might not be quite so hypothetical. No, I don’t mean that the dead will rise from their graves and walk the streets looking for a fresh living brain to dine on. But in very real terms, the dead have an awful lot of dominion over the brains of the living, and that is plenty nightmarish too.
