Dreamed I had a rack of nothing but blank tiles

I'm at a tournament and every single tile I draw is a blank — seven of them, then eight, then the bag won't stop giving me blanks. The board is empty and the clock is running and I keep trying to play a word that isn't there, because a blank with no letter on it is just a small white rectangle that means nothing. Woke up with my hands flat on the mattress, still trying to spell something.
