I'm writing this at 10pm, so whatever memories I had this morning about my dream are long diluted now.

The major part was that I dreamt my mouth was full of glass, as in broken glass from a broken windscreen.

I remember being happily talking to someone, and then something happened and I started to feel broken glass in my mouth. It did not cut, and felt more than anything else like very coarse sand, dry, almost pebble-like. I spit it out and after a short time my mouth filled with glass again.

I don't remember if I was doing something to fill my mouth with glass, like actually putting it in there myself, or whether it was just filling up without me having any say in it. I think it was the former.
