Chew

From a dream I had a while ago: 
Upon reaching the shores of a river in a desert I walked the banks wondering where to go next. Suddenly a young woman appeared before me, her eyes filled with terror as she gazes at me like I'm death itself, as she ran, I chased after her out of curiosity. The pursuit led me to a dark part of the a gulch where "it" resides. The young woman stopped, staring at the monstrosity before her, a huge cliff towered before us, but as I gazed at the cliffs I realized the rocks were beginning to resemble flesh where the cliff meets the ground, and there, sat the most horrible mouth I'd had ever seen, a mixture of broken teeth, grasping arms, decaying bones and transparent fleshy gum pulsed. The woman stood there silently, then looked back at me, her smile told me everything, "this was the end". She sprinted full force towards the mouth and was instantly pulled in, the horrible sounds of grinding teeth, crunching flesh and snapping bones followed. I looked on in shock as I try to process the horror I just witnessed. 
Then, I awoke, cold sweat drenching my shirt and blanket. I relaxed as I felt my toes and the ends of my fingers again, and fell right back into an even deeper and darker sleep.
