Had a dream about an immortal martial artist who was trying find out why he was immortal. It was set in Greek, or Roman times. The guy was being followed around by a tall blond guy who had a little pixie that followed him around. The tall guy wasn’t friends with the fighter but was trying to find out about him. The fighter kept beating up what were, essentially, zombies that came at him in great waves. They were never able to advance far enough to put the tall guy in danger, and he never helped because the other guy was so fast he would just get in the way. The fighter could be hurt, but nothing would kill him and he was badly scarred all over his body. He could clearly feel pain too, but he was apparently almost immune to it when he was focused on a fight. The dream ended as another wave of monsters set upon the hero while he was descending into a cave.
