Moving as one

I'm on the train, earphones plugged-in and standing, face pressed-up against an old man's musty back. The beat quickens and I begin to move, subtle little tick-tack-toes at first, but expanding as I'm overwhelmed by the music. There's reaction, around me, people begin to jerk involuntarily at first, then fall into the irrisistable beatscape, that has suddenly engulfed the whole carriage. All are synchronized, and we are elevated to ecstasy, with the carriage roof bursting open, letting-in diamond shaped fuzzy snow flakes, that float down onto our upturned faces. We all sparkle and glitter, emitting pulsating light show fireworks, spreading ever outward.
