In a world where humanity has surrendered the ability to dream in exchange for prolonging life, rogue "fantasmers" continue to tug at their imaginations. One such creature remains entranced by the fading illusions of the dreamworld, adrift in reverie, clinging to visions no one else can see — until a woman appears. Gifted with the rare power to perceive these illusions for what they truly are, she chooses to enter the monster’s dreams, determined to uncover the truth that lies hidden within.
