Faceless Haunter

In my nightmare, I was in a desert, but it wasn't hot, it was freezing cold. I was running from someone, but I didn't know who. Every time I tried to see his face, it was just a blur. I was running for what seemed like miles, and I thought he would never catch me. But then I turned around, and he was right in front of me. I couldn't see his face, but I knew it was him. He grabbed me, and I woke up.
