In a world where dreams and reality intertwine, players step into the shoes of Isaac, a dream architect who discovers that people's nightmares are manifesting in the waking world. As dreams begin to invade daily life, affecting relationships, careers, and sanity, Isaac must travel through a surreal series of mindscapes—each reflecting the fears and anxieties of different individuals. Players interact with twisted versions of their own memories and fears, solve puzzles using dream logic, and confront manifestations of terror to restore peace. With choices affecting not only the outcome of dreams but also the real world, the game poses the question: whose nightmare is truly in control?
