last night i had the "teeth falling out" dream.

I had that dream recurringly. So much so that I consulted various dream interpretation books/sites. It hints at a fear of/concern about death. However, since I've actually had to have a tooth surgically removed, I haven't had the dream since! Not that I'd recommend the cure, mind you.

i dreamt of a 30s-style revue with girls in gold spangled caps and a man in yellow coattails and tights (like a big chicken) wearing a top hat ~ and everybody dancing with mesh-bagged fleshy-colored grapefruits

You may wish to stay away from the Welsh rarebit.
