In a dystopian world where dreams are traded like commodities, players assume the role of a 'dream dealer' who navigates through a surreal marketplace filled with chaotic, shifting nightmares. Each nightmare presents unique challenges and riddles shaped by the fear and anxieties of the dreamers. Players must outwit other dealers, confront personal fears, and strike questionable deals to uncover the mystery of why these nightmares are collecting in the market, while managing their own sanity as reality blurs with the dream world. Each choice alters the narrative, leading to multiple endings based on how well players handle their own nightmares and the nightmares of others.
