Having experienced two different (though eerily similar) zombie dreams in the past few months, I'm inclined to think that the two are related and, in fact, I suspect they're about quitting smoking.
If I had to guess, the zombies would represent my cigarette habit (an inescapable force that's intent on taking my life). In both dreams, my primary concern was whether I had enough ammo to properly defend myself against them. That seems like a pretty obvious representation of fears that I won't be able to kick the habit.
I don't recall ever having something this close to a recurring dream before, so I really am inclined to think these symbols meaningful, and not just random, unconscious brain firings...
