It's not the same dream over and over again, but I've been having the same kind of thing happen. Recently I have been having this scenario more and more often in dreams... My teeth fall out. o.O I end up having to spit them out in fragments. Last night I had this scenario again, and I actually remember spitting the teeth and fragments of teeth into a large plastic mixing bowl full of tooth fragments, which I knew were all my own. It was almost full. O.o

I think I remember reading something about teeth falling out, but I can't remember what it was or if it was my imagination. <_<
