I guess the underlying question is whether creativity comes from real-life experience in some form, so if you write the line "When she comes walking down the street, I wanna sweep her right off her feet, take her home and take her to bed with me" should this be accepted as fiction and is it paranoid to imagine that the writer has actually seen someone he wants to do that to?!
