I watched this movie once that didn’t make it to theatre’s that was burned from a relative of mine.

He was a book writer and would have nightmares about a guy breaking into his house and beating him to death. He would talk to his therapist but come to find out, in real life that was his doctor. His brother died years ago and when he takes a vaca to get away and write,  he runs into his brother  at a diner in the middle of no where and doesn’t believe it. They end up spending the few days together till he thinks his brother poisoned him but really he is slowly dying from cancer.
