You open the door and find yourself in a room with mirrors for walls. All seems normal - at first. But you could swear you see your reflection move of its own volition, out of the corner of your eye. As time passes a nagging doubt will form in the back of your mind: is that your reflection, or are you the reflection? If you smash the glass, will you be free? Give in to the urge and smash it, and you will find yourself out in the hall, disoriented and with minor glass cuts on your hands. Resist the urge, and your reflection will smash the glass instead, before emerging from the shards and strangling you. You will then find yourself out in the hall, disoriented and with strangulation marks on your neck. Only four minutes have passed.
