I'm talking about the narrator of Fight Club actually just making up Tyler Durden while he himself is pulling all the strings, or Teddy from Shutter Island actually being a mental patient, not a U.S. Marshal on an investigation. (Excuse me if I remember the specifics wrong since it's been a while since I've read those books.) Do you enjoy these types of plot twists? Or would you have preferred these stories if they had ended with some sort of villain reveal, or any other type of plot twist that doesn't include the main character being crazy? For those of you who enjoy these plot twists, but don't feel they necessarily fit all narratives, you can read the basic idea of my book below and see what you feel would work best for my particular story. It is about a writer who, after suffering great personal tragedy, decides to isolate himself in his rich (now dead) father's ranch, where he delves into the story of his next novel. At one point, he creates a room that is related to the plot of his book (a specific kind of mental torture room), in an attempt to experience what that kind of torture would be like, the idea being that he can then write a more realistic depiction of the torture while still being able to leave whenever he wants. But one day he gets locked inside and is then confronted by characters who mentally torture and abuse him while he tries to escape from his own torture room. Would you find the ending more enjoyable if it turns out that the main character actually locked himself in that room, and that all the figures who tortured him were just hallucinations/visual representations of various things he has struggled with in his life, or people he had hurt? Or would you prefer it if the book ended with the villain being revealed as someone who hated him/wanted revenge against him for something he did, and so on? Thanks for any advice you may have!
