Spitting Out Chunks Of My Teeth!
I've had this dream before: I am in a social situation and piece-by-piece, I start spitting out chunks of my teeth.
Sometimes (in the dream) I feel my teeth with my tounge and they are all loose. I pull them out and not only is it my teeth, but the entire root of the tooth. In the dream I know that when I smile, I only have a few teeth left, but more pieces keep falling into my hand.
