sometimes they start out totally normal, but then someone eats the fish, or goes for a piss in the woods, and comes back with blood lust. other times there are zombies right from the start.. sometimes i fuck a zombie, just cause she's hot. there was this one time i let them turn me into a zombie.. no wait it was a vampire, but there were zombies there too. it was actually kinda cool. anyway, what the hell's it about?
i love zombie dreams. once, i got bit in one and woke up with a flu that came with all the symptoms of turning into a zombie in Return of the Living Dead: joints froze up, cold, couldn't move very fast, moaning.... but yea, i don't think they themselves mean anything. i'd say, analize your feelings in the dream and see where they might be comming from. like if you feel chased or if you feel scared and betrayed (from people turning into zombies/monsters).
