Undead – See Zombie. Dreaming about the undead while you are asleep is never a good thing. This dream is brought upon many times by watching science fiction movies to excess. However, the good news is that zombies are mostly harmless. If you stay away from them they will typically only half-heartedly try to eat you in dreams. This is actually proven to be true due to a recent survey. The undead can also represent a repressed desire to finalize the passing of a loved one.
