In a world where nightmares are collective experiences shared by society, you play as a psychonaut who can enter and manipulate the dreams of others. Faced with overlapping fears, traumas, and bizarre surreal landscapes, you must navigate through different citizens' nightmares to uncover a mysterious force corrupting the dreamscape. Players will solve puzzles, form alliances with dream denizens, and confront phobias—all while racing against time to prevent the collapse of reality itself. Your choices will impact not only the nightmares you explore but also the lives of those trapped within, leading to multiple endings.
