You know how sometimes in your dreams you try to move, run, punch, jump, whatver, but you can't? Well that's because when you're like, as asleep as you can be (not sure what the official term for that is.. maybe when you're in a state of R.E.M. sleep?) you're pretty much paralised. When you're that deep asleep and you try and move quickly it feels like you can't because in real life you can't.

So your senses must still carry over to your 'dream world'. That's why I think dreams about losing teeth are less profound as you suggested, Lulu. Alot of people drool when asleep, in fact everyone does to some extent when they're deeply asleep, and that's why you wake up sometimes with a horrible taste and texture in your mouth.. I think it's this feeling that carries over to your dream, and makes some people dream about losing teeth and such.

After going out and getting stupid drunk and passing out on a sofa I had a dream in which my mouth tasted like beer and cigarettes all the way through.. lol.. I think the losing teeth thing is the same concept.
