Perhaps "I was lost in the rye" is a reference to Salinger's Catcher in the Rye? The line "I'm just another misguided child of fiction" could support a Catcher reference... and the lines right after that, "School kids are shouting in the streets / And I wish I was signing in their wide-eyed chorus," is reminiscent of the scenes in Catcher in the Rye when Holden sees a little boy singing happily even though his parents are ignoring him and when Holden visits his sister's school. The city setting also brings to mind Holden's quest for enlightenment.

Maybe; maybe not. Something to consider.
