Twixt (2011) on Netflix

The decadent writer of witch tales Hall Baltimore travels to Swann Valley, a small town where people go to be forgotten, as part of his tour to promote his recent novel. The town does not have a book store, and Hall stays in a hardware store waiting for his non-existent fans. Later Sheriff Bobby LaGrange, who is an aspirant writer, arrives and tells that he is his fan and asks for an autograph in his book. Then he asks if Hall could read his recent work and invites him to go to the morgue to see the body of a victim of a serial-killer that was murdered with a stake through her heart. Then Hall goes to a coffee shop and discovers that Edgar Allan Poe has once come to a hotel in the town where twelve children have been murdered. He goes to his room and tells his wife through Skype that he is going to write a novel based on the weird events at Swann Valley. Hall falls sleep and in his dream, he walks along a park where he meets the twelve year-old Virginia, a.k.a. "V", who tells that is her fan, and then with Edgar Allan Poe. On the next morning, Hall decides to team-up with Bobby to write a story based on his idea, but he is blocked and uses pills to sleep and dream. Along the creation process, Hall entwines reality with his dreams.
