Last night I dreamed the dance floor was an elevator

I'm setting up my DJ booth in this dim hotel ballroom, but the dance floor is just an elevator. Every time I drop a beat, the doors open and strangers step in, press a floor, and stare at themselves in the mirrored walls. No one dances — they just ride, and I keep spinning for the hum of the cables. I woke up still feeling the button under my thumb.
