I just finished reading Slaughterhouse V and near the end I felt disappointed at what I think are conceits made that explain away all of Billy Pilgrim's experiences in time travel as manufacturings of his imagination.
He finds out about Montana in a German porno store when he sees a picture of her. He sees her locket in the same store. Many other things that 'happen' on Tralfamadore are referenced in other scenes in the book, which makes me think that when Billy hit his head in the plane crash that he begins to mix reality and his imagination into the alien abduction story that he makes up.
Also, nearly any time that Billy is 'back in the war' or 'time traveling' he seems to have fallen asleep and is usually woken up back in the present.
As I started to think about it, I liked the book less because it was less fantastic.
Any thoughts?
