Insidious

Josh and Renai Lambert move into a new home with their sons Dalton and Foster and infant daughter. Dalton explores the attic and the next morning cannot be woken — he is in an inexplicable coma with no medical cause. Strange figures begin appearing in the house. Josh's mother Lorraine contacts Elise Rainier, a psychic who reveals the truth: Dalton is an astral projector who has traveled too deep into a realm of the dead called The Further and cannot find his way back. Multiple entities want to possess his empty body; the most powerful is a red-faced demon who has been pursuing Dalton for years. Josh, who has suppressed his own childhood ability to project, must enter The Further to retrieve his son. He navigates the nightmarish landscape of lingering dead, finds Dalton, and pulls him back. Upon their return, Elise photographs Josh as he reunites with the family — and then is killed off-screen. The photograph reveals an old woman's spirit followed Josh back and now inhabits him.
