3x13 Ghostfacers

Sam and Dean investigate the haunted Morton House in Appleton, Wisconsin , and come across supernatural-enthusiasts Harry Spangler (Travis Wester) and Ed Zeddmore (A. J. Buckley). They are shooting the pilot for their reality show Ghostfacers along with Ed's adopted sister Maggie, gay intern Corbett (Dustin Milligan), and cameraman Spruce. According to legend, the spirit of Freeman Daggett returns every leap year to bring more victims to the house. The group comes across a ghost reliving his death, which the Winchesters call a harmless "death echo". Corbett soon disappears, and the rest are unable to escape before midnight; the spirit locks down the house, trapping its inhabitants. In their search for Corbett, they come across the home office of Daggett. The janitor of the local hospital, he used to bring home corpses from the morgue to "play" with. Sam suddenly vanishes and finds himself with Corbett, both tied to chairs at a birthday-party setup. The spirit appears and kills Corbett, then placing a party hat onto Sam's head. As Dean enters the bomb shelter holding Sam, the others place themselves in a circle of salt—a ghost deterrent—and watch a death echo of Corbett. Ed, who Corbett was in love with, talks Corbett out of the death echo. His spirit confronts Daggett, putting him to rest. Before departing the next day, Sam and Dean wipe all of the Ghostfacers footage with an electromagnet
