Lily (Sylvia Summers) is the primary antagonist of the 1986 horror movie "Dreamaniac".
Lily is a succubus who appears inside the dream of Satanism-practicing protagonist Adam, though she doesn't stay inside his dreams for long. Lily crashes a party hosted by Adam's girlfriend, Pat (Ashlyn Gere) and her sister Jodi, and begins sadistically murdering all of the party-goers one by one. The ending of the film alludes to the story having all been a screenplay idea for an unnamed man. Despite whether or not the events prior to this did in fact occur, one certainty is the existence of Lily; proven true by the film's final shot, where she appears and then proceeds to kill the man.
