Meta-fiction
My boss wrote a fictional story about his daughter. In the story, she was a cop for the RCMP who was dating a psychotic pharmacist. Years after the story, the daughter is engaged to a pharacist. It's uncertain if he's psychotic or not.

In the Invisibles, Grant Morrison based a character on himself called King Mob. In the comics, King Mob was captured and tortured by the Enemy and was almost killed. When the book went to press, Morrison suffered the same effects as his character and was only cured when the issue where King Mob was cured went to press.

I think that the line between our reality and fiction is thinner than we'd like to think.
