The narrator from Fight Club is Jason Cole's son from 12 Monkeys. He would regularly visit his father in the mental insitution, but his father neglected him, so the Narrator bonded with Brad Pitt's character. Due to frequently being surrounded by such an environment and genetic predisposition, he develops schitzophrenia/insomnia, and creates a platonic self-image; Tyler Durden.
EDIT: Note that Brad Pitt's character in 12 monkeys clearly has daddy issues, which would be something that our infant Narrator could identify himself with if this theory made any sense at all...
