The Boogeyman (1980) 

 

The film's prologue opens in the 1960s, when a young boy conspires with his sister to murder their mother's cruel and abusive lover. Flash forward to the present, with both siblings scarred by the emotional demons of their past: the boy has remained mute since that fateful day, and his sister (Suzanna Love, aka Mrs. Lommel) is tormented by nightmares. If that weren't enough, a literal demon is released when the old mirror which paid witness to their deed is shattered, releasing their victim's enraged spirit to seek bloody revenge... and he's not too particular about who he takes it out on.  - AMG
