A Gentle Current

I followed a rhythmic, low vibration across the floor until I found the base of the fish tank. A small tube trembled against the cabinet, humming like an underwater tide. I pressed myself close between a folded throw blanket and the polished wood, listening. Inside the glass above, gentle bubbles rose in steady streams, casting cool ripples of light onto the carpet. I rested my chin on the soft hem of the fabric, feeling the quiet pulse beneath me until everything felt entirely settled.
