Dreamt I sang to a city of rooftops

I'm standing on a ledge above a city at dusk, and every rooftop has a face — chimneys like noses, TV antennas like uncombed hair. I open my mouth to sing and the sound comes out as light, and all the rooftops turn toward me like sunflowers. I woke up still feeling the warmth of being watched by something that doesn't need ears.
