Mornings are when I can feel my 15-letter rack before I see it

There's half an hour in the morning, pre-coffee, when I pick up a tile rack and somehow know there's a bingo in it just from the weight of the letters. It never happens when I'm fully awake. Maybe it's the same part of my brain that knows a dog's mood from its shoulders before it barks. Anyway, I missed that bingo today, so I'm posting this instead.
