A Quiet Tap

Urrgh... The light around me was stark and bright white. I lifted one square foot and brought it down with a firm, muffled tap. It worked. I could move. Slowly, I raised both arms straight ahead, leaning forward until the edge of my hands brushed the cool, flat surface below. ...Hrrn. I lowered my arms to my sides and stood motionless, anchored firmly in the quiet white space.
