Dream Ledger for Me not You

I remember being in a place that looked very much like the concession area of a baseball stadium. There were many people there, most of them I didn't know. They were hiding because out on the field was an immortal and he was going to swallow some girl's soul. I'm not sure what he was exactly, but it was clear that he wasn't fully human. There was a dark purplish mist-like energy flowing out of him. He looked very human, but he had claw-like hands and feet, and all of his teeth were pointed. I don't know what came over me, but I ran out there and challenged him to a duel for the woman's soul. I had no special powers that I knew of, but I had an irresistible urge to fight this creature. I must have known him somehow, because he recognised me and laughed at my challenge.
"It's been so long" He screeched at me, "Do you still remember me?". My silence to that question must have given it away. "You don't!" He said angrily, "Challenge accepted, I'll have to grind the memory of me in deeper". Images flashed too fast for me to make out. Next thing I know the stadium is ruined and we're facing each other breathing very heavily. The girl is gone, I don't know what happened to her. I have in my left hand a long, thin sword. The creature runs away, vowing revenge, and everything goes black.
