I believe this may have been one of those haunted house documentary / reconstruction type programs. There was a young girl who was often talking to what her parents believed to be her imaginary friends although she insisted they were real. At one point the mother is alone in the house for the day and hears noises and later tells the husband she is starting to believe the daughter. Later when the girl is bed she turns around and we see a man and woman staring down at her and she freaks out screaming “go away”. Thank you.
