MY boyfriend had this dream last night that scared him a lot! He was out in the woods with a group of people, there wasn't much of them left and the world was being taken over by zombies. They were low on ammo and their chances of survival were going down hill. Then a new breed of super-zombies appeared on the scene and went after them. He woke up when one of the zombies was right in front of him about to kill him.
The zombies could stand for something that is threatening him in real life. I think of zombies as things that have no emotions or compassion and no sense of morality, that just try to fulfill their basic needs (eat). Could the dream be a warning about needing to be more in touch with his feelings or the feelings of others?
