What is the main conflict in We Live by What We See at Night by Martin Espada?

In the poem's final lines, readers find the source of the poem's title, as well as a return to the world of dream. When the poet says he lives by what he sees at night with his eyes closed, perhaps he's suggesting that the dreams of Puerto Rico help sustain him through the harsh realities of the New York projects. Having come from a long line of exiled people, the poet learns from his father how to live on dream, hope and myth.
