Ghost Whisperer Episode 5.13 Living Nightmare

A strange man stumbles into the hospital covered in blood. He's scared and seems as though he isn't quite aware what's going on only that some man with a knife was chasing after him. Jim quickly takes charge as Melinda, at the hospital visiting Jim, sees a male ghost who warns her that nothing they do will help or save him. "He's a dead man." The hospital identifies the man as Robert Wharton and they discover that although the blood on him was his, his injuries were minor - no brutal knife slashings as he was afraid of. When Jim tries to talk with Robert, he once again is unsure of what's happening to him, what he's seen or what he's done. He keeps having images of a woman being slashed but he can't remember anything. The only thing that is sure is that Robert doesn't seem to be able to fall asleep. The male ghost visits Melinda again and she, Eli and Ned try to figure out what's going on. They finally locate Robert's girlfriend and father. His girlfriend had been very worried about him, having seen a change come over him in the last few weeks where Robert had been agitated and acting strangely. His father admits that Robert was adopted and Melinda discovers the male ghost who's been haunting around is Robert's real father. He's staying close to Robert and keeping him from sleeping. From his medical records, they find that Robert may have inherited a fatal disease from his father called Fatal Familial Insomnia which renders the body incapable of falling asleep. Robert's father had it and had started to see "demons". When his mother tired to help, his father killed her, slashing her with the aforementioned knife in Robert's visions. The hospital does tests on Robert and they discover he doesn't have the disease and the "demons" that Robert's father's ghost was fearful of were not going to harm him. His ghost found peace thanks to Melinda, and Robert was finally able to get some sleep.
