Let the dreams be real

There's a serial child abductor and murderer nicknamed "The Grabber" at large! A sadistic fuck who kidnaps school children and locks them in the basement of his house. The dungeon has a defunct phone that gives real or imaginary comfort to the locked children. We are lead to believe there's former victims on the other end of the line! A chilling story (courtesy of Joe Hill), but the unexplained bits turn down the thrills a notch.
