Although my opinion may not be well received, I believe that this song (for me) is about America. I can only support this perspective based on "angels on the moon" (our Astronauts from the late 60's) and the lyrics that direct attention to the tragedy of 9/11 (New York City angels and the rivers of our blood). The lyrics "don't wake me cause I'm dreaming of angels on the moon" may pertain to the fact that we are still waxing nostalgic about our accomplishments in the space program from years past (and the international stardom being the result), and as a result, have become naieve about our mortality as a nation. The song's overall theme, although energetic, is laced with melancholy concerning not wanting to know "if I'm dying", and this may be directly related to our terrible financial and cultural crisis, something that very well may destroy America. We may, in fact, be in denial about our own death as a country.
