Alice felt a smooth, flat surface against her cheek. She opened her eyes to see she was lying on a clear, plastic floor, illuminated from behind my huge monitors. As she fully opened her eyes and stood up, she saw there were four walls around her, and a ceiling, each also covered in a clear plastic with huge monitors behind them faintly glowing grey. She was inside a plastic box, about three meters in each dimension.
As she sat, confused, the monitors suddenly started to display text on every wall, the floor and ceiling, bold white on black.
It read, "STAND UP."
She paused for a moment, still leaning up on the floor, somewhat confused by her surroundings.
A few moments later, the colors inverted - the room was full of blindingly white light and an almost painfully loud noise blared for just a moment. She clutched her ears and squeezed her eyes shut in surprise.
It stopped again. The white text on the black background still read, "STAND UP."
She did as it said, bringing herself to her feet, hopeful that the sensor onslaught wouldn't happen again.
Once she was standing, the text changed, and now read, "ARMS OUT." To the side of the text, was a diagram, showing the outline of a human body standing with arms out to their side. She did as it illustrated.
A red line ran down the walls, which was accompanied by a strange whizzing noise - like she was being scanned. The red line reached the floor and the room was plunged into darkness again.
New text appeared.
"UNDRESS."
