Book of Dreams

I was watching Zombieland and totally just remembered my dream from last night.
I was in a dark cave or castle or something, and this girl fell off a cliff and hit the ground. She didn't move, so I assumed she was dead. I didn't want to just leave her body there, all exposed and whatnot, so I found some white cloth and submerged it in water, so that when I dropped it, it fell straight down on top of her. After it covered her, she leaned up and tried to breathe in, but the wet cloth was suffocating her. She scrambled frantically to remove the sheet, but each time she got one layer off, there was another underneath. The choking and screaming she made was horrible. Eventually she was dead. That was definitely one of the most f'd up dreams I've ever had.
