Tralfamadore; Billy's pretend world

Billy Pilgrim time travels through all different places and times throughout the book, and claims he is abducted by tralfamdorians. I think that Billy is definitlty imaging the whole tralfamdorian experience. When Billy is on planet Tralfalfamadore he "learns new things", but in reality, he is just remembering and looking back on things he had already learned. For example, the locket that Montana Wildhack wore with the quote "God grant me the serenity to accept the things I cannot change, courage to chant the things I can, and wisdom always to tell the difference." (Vonnegut 209) But this poem was also used in chapter 3 when Billy was reading the posters on his office wall at work. Billy used Tralfalfamadore as an alternate reality. He came up with the setting when he started reading Kilgore Trouts sci-fi books, and has taken little pieces of his daily life to create this world. A world he wants to live in.
