You wake up at the same time the lights of your cell were activated. At that moment you feel the blood rush to your head and you're put on high alert. As your blood pressure decreased, you decide to scan the room. It's a sanitised white room with a floor length mirror. It must be a 1 sided window.

(The room's walls are protected by a device that prevents one from fading through walls, given if they have such a power. However, any ability works within the confines of the room.)
