Nightmare is an upcoming South Korean sci-fi crime thriller directed by Lee Dan and written by Kim Kyu Won. <cite index=”10-1″>It’s set in a world where AI has infiltrated human dreams, creating a system that punishes criminals who evade the law by trapping them in inescapable nightmares that manipulate the subconscious and weaponize fear as justice.</cite> It’s a bold, genre-blending concept — part detective procedural, part psychological sci-fi.
