Harold (7:19)

One night, during a thunder storm, a fake psychic (named Clara Voyant) gets a call from a woman named Mabel, who wants her to contact someone named Harold, and tell him to stop hurting people. Then the power goes out. As we see Clara trying repeatedly to light a candle... a figure, presumably Harold, gets closer to her. That's pretty much all I can tell you. But it's fairly creepy.
