Dream 04: Demons + Secrets (Reoccurs)

I was in a library looking around. I found an old brown leather book that was huge. It had to have at least 2-3,000 pages in it. It was locked shut with chains around it. I tried to open it but I didn't succeed. I heard everyone starting to scream, shoving me out of the way, running out of the library. I just stood there still holding the book. I was then alone. Black smoke started to fill the room and I heard someone behind me. I turned around and saw the same demon as in my first dream. I wasn't afraid but I felt safe and protected. He gave an evil grin and then I woke up.
