Dylan is a master writer of poems/songs and apparently interested in little else. Through his gift of verse/song he was able to create his own abstract world. It's a pleasure to watch the genius at work, in a mere joyful construction of verses by observation of real world. See how easily he make all possible combinations between cigarettes, birds, place, dog and other elements that he just saw in a pet store. It's really savant way of expression because brings meaning to words and places who nobody would imagine before. It's sort of creativity which creates by transformations. Aspergers do it as usual.
