Last night I dreamed the tiles rearranged themselves into a word I didn't know

I'm standing over a board mid-game, and every rack is just vowels — all of them, even the Y's. Then someone reaches in and swaps them for a word that isn't in any dictionary: CLOUDBRASS. I woke up trying to figure out its score. Still don't know what it means, but it felt like the board knew something I didn't.
