"Ghouli" is the fifth episode of the eleventh season of the American science fiction television series The X-Files.
The show centers on FBI special agents who work on unsolved paranormal cases called X-Files, focusing on the investigations of Fox Mulder (David Duchovny), and Dana Scully (Gillian Anderson) after their reinstatement in the FBI.
Dana Scully (Gillian Anderson) opens her eyes in the dark, sensing a presence behind her as she lies on a bed in a strange house.
Fox Mulder (David Duchovny) theorizes that the experience is a type of sleep paralysis.
Aboard the ship, Scully notices a bloody handprint left by one of the girls on the bridge and questions who made the call.
Hearing two gunshots, the agents dash into the house and discover a man and a woman's bodies on the floor.
A third shot is heard from the upstairs, where Scully finds the bleeding corpse of Jackson Van De Kamp.
The agents search Jackson's room and find a book by Peter Wong, a pickup artist.
Scully is lying on a couch and has another experience with sleep paralysis, with flashes to the bridge, the UFO hovering above, and the bloodied alien hand.
Scully runs into the man that she spotted at the docks, Peter Wong (François Chau).
Walter Skinner (Mitch Pileggi) meets with Mulder at the Chimera, telling him to drop the investigation.
Cornered inside a supply closet, he resorts to tricking one of the operatives into thinking that the other is a monster, killing him.
[1] Wong was inspired to write this episode after having an experience with sleep paralysis in Mexico as he was shooting a movie.
