This poem reminds me of a book called Inside Out. It is about this boy with schizophrinia (sp) and he can't get to his medicine because the store he went to is being held up. Well the entire time all the other people there are freaking out he is battling his inner deams. At one point the voices start screaming and yet everybody is yelling at him to shut-up because they don't understand.
It was a good book and your poem about inner deamons reminded me of that book.
