Aunt Helena, played by Irene Dailey, is a character in the 1979 film The Amityville Horror.
Aunt Helena visits Kathy Lutz at 112 Ocean Avenue soon after the Lutzs move in. She enters the home with some flowers as a homewarming gift. As she walks through the main corridor, a disembodied voice tells her to "get out".
By the time Kathy greets her, she has to suddenly leave the home. She drives away a little distance and becomes physically sick, throwing up on the street. Later during the wedding reception for Jimmy, she tells Kathy she doesn't know what came over her.
