The ability to dream can be uniquely human. These dreams exist without any purpose other than achievement. In many cases it is a dream, not an instinct, that guides human action. Certainly dreams are central to human life. Since one of the main purposes of literature is to reflect on that life, it is necessary to include some dreams. The realization of the dream completely depends on the author and what are his thoughts on the realization of dreams. Tennessee Williams, William Faulkner, and Zora Neale Hurston all use certain literary elements to create their theme of dream fulfillment, which is seen and portrayed differently by each: gravely, by Williams; pessimistically, by Faulkner; and with a modicum of optimism on Hurston's part. There is hardly a better adjective than "sad" to describe Williams' attitude toward dreams and their fulfillment in his play "The Glass Menagerie." Williams does not treat dreams violently and harshly, but sadly and touchingly, using symbolism and stage lighting. Amanda's daffodil dress, a throwback to times gone by, is an important symbol. The revival of the dress, a remnant of Amanda's courtship days, shows the extent to which her dream of living through Laura pervades her life. The use of the "girl's" outfit makes it seem as if Jim is visiting Amanda, rather than Laura, taking Amanda back to her happier days (Williams 53). The clearest and most important symbol is Laura's glass unicorn. It represents it; his changes mirror hers. He only puts the unicorn outside when Jim arrives and, not entirely intentionally, opens up to him. As Laura shares her first dance with Jim, the unicorn falls and its horn, the only thing that distinguishes it and separates it from the other horses, breaks... halfway down the page... shback, Hurston notes that you can help others with their dreams and still realize your own, as long as other people's dreams don't become permanent priorities. People's thoughts about dreams vary, and therefore dreams are shown in different ways throughout literature. All three authors agree that achieving a dream is not guaranteed; takes a bit of work. From there, they use different techniques to refine their opinions. In their respective novels, Hurston offers some hope to dreaming humanity, while Faulkner scoffs and tells them what to do, and Williams urges them to give up while there is still time to avoid the pain. Differing opinions like these are found across a wide range of literature and offer readers comprehensive food for thought and the chance to think and form their own opinions, in this case, about the feasibility of dreams..
