The W of Oz can relate to The Matrix, The Chronicles of Narnia and Fight Club in several ways. The W of Oz has Dorthy wake up at the end, similar to The Matix's other universe, the different world in Narnia, and how Fight Club had a duel life. Reality is not real in any of these films. Dorthy has a dream, Neo gets plugged in to the Matrix, The C of Narnia is in an alternate universe and Fight Club is a made up in one man's head. The point of these similarities is maybe not that reality is relative, but that reality isn't real... whatever that means...
