Silence is starting to sound like something

I've been conducting this piece in my head during night shifts, and the rests are getting louder than the notes. It's like the ICU on a quiet hour — all the machines humming underneath, and if you stop listening for alarms you can hear the building breathe. Maybe I'm just trying to make friends with the quiet before I have to sit in it alone. Music's the only thing that's made sense of it so far.
