I used to have the teeth falling/rotting/breaking dream A LOT. I don't know if it's timing or what but usually soon after I'd get into a huge fight with a loved one and close people did pass away (but again this is likely coincidental).

I'm inclined to believe the dream as a kind of warning that I'm about to have a big fight with a loved one.

Needless to say, I HATE those dreams.

But back to more important things, maybe you should get yourself to a hospital? Or at least ask a close friend to keep you company?

Hope you get well soon!
