For prompt 10: "How long has it been?"
His world consisted of a white cube.
White
An eerie white light came from all six walls, preventing night from ever invading the room. He hadn't seen a shadow since he got tossed inside. His memories were blurry white. Did he ever have a real shadow of his own, or had it always been white like now?
White light everywhere.
Time stood still in the cube. Eternally silent. Eternally white. Dragged on and speed up, until he was sure that even his heartbeat had creased, had it not been a constant white throbbing in his ears.
White buzzing in his head. Twisting in his mouth.
How long had it been now? He had no way to count the hours, the days, the endless white years?
White. White. Forever white. Devouring white.
White. In one corner of the cube stood a white bucket. This was the room's only feature. He had no bed, no blanket. Not even a sink to wash his white face.
White. White. White. A melody in his head. On repeat. White. White. White. He can sing along now. White. White.
White. There was nothing to see other than white. Nothing to hear. No one came to see or speak to him. Had he not still been fed, he would have thought they had forgotten him. White.
White.
White. Like he had forgotten them. Who were they?
White. White. White.
White. He was served food at random times. Sometimes he was still full when it arrived, often he felt half-starved. It came in the form of a white power shake, served in a white plastic cup. It tasted of nothing. It tasted white. White like everything in here.
White! One wall would open soundlessly into another small white room, and a full cup and an empty white bucket would be inside. The wall would only close again once he had placed the old bucket and plate inside and stepped away. If he refused, he would not get food until he passed out. He remembered that much. He remembered white. So much white! Nothing else than white as he floated high above and felt nothing. Felt wonderful white!
Whitewhitewhite! He wore no clothes. He was white! White, like the cube. White, like everything important. He remembered spending a long time huddling embarrassed in a corner, trying to cover himself as he felt eyes watching from all sides. A white existence! He didn't think they were still watching. He didn't care if they were.
White. The temperature was constant and white, neither cold nor warm. Sometimes, he still shivered or sweated for no reason.
Repeat.

White colours flashed along the walls
White. White. White shouting. White. White. White. Repeat. White. White. White.
Whitewhitewhite! Whitewhitewhite! White crying? Somewhere close. No more white. He wanted white!
Only white noise in his head, yet he treasured it. Choking white. Nice white. Quiet white.
Anything other than the white static that made up his brain.
