Blood Song (also known as Dream Slayer) is a 1982 American slasher film directed Alan J. Levi, produced by Frank Avianca and Lenny Montana, and starring Frankie Avalon and Donna Wilkes. It follows a crippled young woman in a coastal Oregon town who is stalked by a hatchet-wielding psychopath from whom she once received a blood transfusion. The movie is notable for a different style of performance from Avalon.

Based on a short story by Joseph Shink, Blood Song was adapted by Shink along with producers Avianca and Montana. The film was shot in the fall of 1980 in Coos Bay and Coquille, Oregon. While not prosecuted for obscenity, the film was seized and confiscated in the United Kingdom under Section 3 of the Obscene Publications Act 1959 during the "video nasty" panic.
