The player takes the role of Thomas, a man who "wakes up" from one nightmare and into another. As the player navigates Thomas throughout the game, the nightmares become progressively worse, including the horrifying monsters that lurk within them. Each time Thomas dies in a nightmare, comes across some serious cause of depression, or commits self-harm, he will "wake up" again in either the same nightmare as before, or into a different one.
