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.
Mary Shelley uses a multiple narrative in Frankenstein.
If you are talking about the following five lines:
Two roads diverged in a yellow wood,And sorry I could not travel bothAnd be one traveler, long I stoodAnd looked down one as far as I couldTo where it bent in the undergrowth;"
Then we can say that the writer remembers being in a yellow wood at fork in the trail. While you read this part you can see that the path is probably away from normal modes of transportation. He suggests in the poem that he will not likely come this way again, further backing the idea this is not a familiar place. The place called "Yellow wood" is named by the idea of <span>fall with the leaves having turned colors away from green.</span>
The fine line between love and hate.
Hope this helps.
