I think I heard the same interview that Scott did. I remember him saying that a stalker was just a character that fascinated him. And the part where he says "there you are to rape me and try on my clothes" was because Brad Pitt (I think) had a stalker who broke into his house. When they found him he was going through Brad's clothes and trying them on.
So basically, it's not based on a personal experience.
