Keanuphobia - fear of Keanu Reeves, portrayed in the Dean Koontz book, False Memory, where a woman has an irrational fear of Keanu Reeves and has to see her psychiatrist, Mark Ahriman, each week. He calls her the "Keanuphobe" in his head. She eventually ends up killing her psychiatrist because she believes that he is one of the Machine agents trying to control her.
