Our speaker of "Harlem" presents us with several juicy philosophical questions about dreams. For example, are dreams meant to be thought about or acted upon? Is it a bad thing never to pursue a dream? What happens when someone else prevents you from pursuing your dreams? Our speaker suggests that sometimes we don't have any choice but to defer our dreams, which is quite a tragedy.
Explosion happens accidentally. The final line of "Harlem" makes us think that dreaming is a natural thing that happens out of necessity rather than choice.
