If anyone can shed any light on what is going with me, I would appreciate it...

I have had a dream, probably 3 or 4 times now, that is strange and causing me to wake up acting out the dream. It ususally happens when I get home from work, watch TV and fall asleep on the couch. I keep dreaming about putting things in my mouth. In one dream I think it was a peppermint, but when I put it in my mouth, it turned out to be a piece of plastic. In another one, I put something like a brownie or cookie in my mouth and it turned out to be a hairball. In all cases, I woke up hanging off the couch spitting into the floor, utterly convinced there was something weird in my mouth. When I have come to fully, I am surprised to find myself spitting in my own floor, and there is nothing in mouth. Any ideas? Thanks!
