I could be completely wrong but I reckon he's sort of worried and confused about his real life and the persona he's created through the band. There's an awful lot of references to other songs of his and it's almost like he's forcing himself to believe his own words, or maybe he's struggling to write new words (Get Behind Me Satan is quite an unusual album and almost provides antithesis with Elephant).
