I still vividly remember a few years ago, when I first moved out of town for college.. For some reason my body didn't feel right all day, and when I fell asleep that night, I dreamed a nightmare where my body was being tossed around and I was being pulled. I couldn't wake up at all, but I tried so hard that I finally woke up. But then there I saw a horrible-looking creature pressing down on me, I couldn't close my eyes or move my body, I couldn't even scream. When I finally opened my eyes, I woke up panting. To this day I'm still not sure if what I saw was real or not.
