Mattheo Riddle is plagued by relentless dreams of a mysterious girl who appears every time he falls asleep—silent, haunting, and impossibly real. He doesn’t know who she is or why she’s there, only that her presence unsettles him more than any nightmare ever has. When a new student, y/n, arrives at Hogwarts University, Mattheo is shaken to find she’s the exact girl from his dreams. Convinced she must be a trick or some form of manipulation, he confronts and follows her, desperate for answers. But y/n has no idea who he is—and no explanation for why she’s been living in his mind.
