Rotten rat Teeth falling Out

"I had the most disgusting dream last night. I was standing alone in a dim, quiet room, and something felt wrong in my mouth. A loose, shifting pressure. Then, all at once, my teeth slid free and dropped into my palm like a set of dentures. I looked down at them. They were yellow and rotten, slick and crumbling at the edges, and every one of them was sharp, narrow and pointed like the teeth of a rat. I wanted to throw them away, but my hand wouldn't open. My tongue slid across the empty gums and I felt my stomach twist, a cold wave of nausea rising in my throat. The room seemed to tilt. The teeth felt heavier in my hand, almost alive, and the thought that they had been inside my own mouth made me feel sick all the way through. And then I woke up. My heart was pounding and the sheets were tangled around me. I ran my tongue over my teeth, one by one. They were all there, solid and whole. It was only a dream. The sick feeling lingered for a while, but slowly my breathing settled, and the room came back into focus."
