Insidious: The Red Door

Nine years have passed. Dalton Lambert starts college with no memory of The Further — it was suppressed a second time to protect him and Josh. Josh, whose own memories were suppressed again, has grown cold and distant; Renai has separated from him. Dalton begins experiencing visions during his art class and discovers he is projecting again. In his psyche exists a red door — the barrier erected to seal away his abilities. He opens it. The red-faced demon from the original film is waiting. Josh's buried memories begin resurfacing, drawn by the same supernatural gravity. Father and son are pulled back toward each other and toward The Further. Josh enters the realm to pull Dalton out, confronting the accumulated darkness and trauma sealed behind the door. He seals it permanently by sacrificing his own ability to project. Dalton is freed. Josh's fate is left deliberately unresolved.
