Dylan's somewhat varied 'explanations' of 'Idiot Wind' -- so which is it, Bob?

Dylan has denied that the song is personal, stating in 1985 that:^[20]

I thought I might have gone a little bit too far with "Idiot Wind" ... I didn't really think I was giving away too much; I thought that it seemed so personal that people would think it was about so-and-so who was close to me. It wasn't ... I didn't feel that one was too personal, but I felt it seemed too personal. Which might be the same thing, I don't know. 

In a 1985 interview with Bill Flanagan, Dylan said that although many people thought that "Idiot Wind" and the album Blood on the Tracks related to his life, "It didn't pertain to me. It was just a concept of putting in images that defy time – yesterday, today and tomorrow. I wanted to make them all connect in some kind of a strange way."^[4] 

In his 2004 memoir Chronicles: Volume One, Dylan claimed that Blood on the Tracks was "an entire album based on Chekhov short stories—critics thought it was autobiographical—that was fine."^[29][7]
