In 'Whose Nightmare Is It, Anyway?', players find themselves in a surreal world where the boundaries of reality are twisted. Each player assumes the role of a dream weaver—a character capable of entering and manipulating various nightmares of others. The objective? To navigate these bizarre dreams, solve riddles, and confront dark fears while unearthing secrets about each dreamer's past. Players must cooperate to escape their own nightmares while managing the chaos that ensues when nightmares merge and become unpredictable. Choices impact not only the outcome for the player's character but also the health of the dreamers, leading to multiple endings based on the collective decisions made throughout the game.
