Paprika

Using the DC Mini, a device that lets a therapist enter other people's dreams, psychiatrist Atsuko Chiba treats her patients under a second identity, Paprika. Then prototypes of the device are stolen, and dreams begin spilling out into the waking world. With its inventor Tokita and a detective named Konakawa who is haunted by a recurring nightmare, Atsuko hunts the thief through a world where the line between dream and reality is dissolving.
