In Langston Hughes's poem " I dream a world." The repetition of the word "dream" emphasizes the fact that equality is a desired but seemingly unattainable goal.
In his poem, Hughes dreams of a world where with other men, a man lives harmoniously and happily and that no one look down upon anyone. Further, he states that his dream world insists upon peace and love. Such statement by Hughes and repetition of "I dream a world" insist that the current reality is not same rather men look down upon another man upon their skin color. In his real world, only certain men enjoy the freedom and that he dreams of a world where there is no mar humanity and greed will eradicate.
