A white room, he appears in a white room. Empty, pure and silent. Something is off. Tick, tock. The clock is ticking. The fire is burning. The world is empty, the world is silent. Dreams and nightmares, they are all the same. Maybe accepting the truth, and dealing with it will be easier. Fighting your fears, but also what made them. Fighting people the brought you down. Maybe discovering a different truth.
The reader, are you keeping up? If not, then good. This is not a story that has a straight answer.
Going up-stairs in the subway, a man steps on a plastic cup and falls down, but far from getting severly hurt, he finds himself in a strange place, where no-ending yellow corridors is all to see, and from where is almost impossible to scape. At first, he thinks he is in a coma or in some kind of nightmare, but after starting to feel hungry and thirsty, he relices that maybe everything is real, and he needs to get out before is too late.
