A quiet glow

Everything was still. I blinked my eye... and the warm yellow corridor felt huge. My little arm gave a tiny twitch, gripping the little yellow tube in my grasp. I pressed. A bright circle of white light appeared right on the floor in front of me. I shifted one foot forward... just an inch. The light moved too, quietly brushing against the base of the tall corner wall. I paused, watching the bright spot stay still beside me.
