Dream Deferred

In Dream Deferred, a short poem written by Langston Hughes, the use of similes draws in the imagination behind the poem. At first glance, I thought the poem surely was only to describe what the author really truly thought about his personal dreams. But when I really contemplated the rhetorical questions posed about whether a dream turned into this or that, I found that I had to think of my own personal dreams and aspirations and what happened to them when I gave them up. This genius displayed through the use of like and such descriptive diction brought fourth such vivid memories that I could not help but really enjoy the poem.
The second aspect that I truly admired in the poem was his ability to call forward so many various memories. By beginning the poem with a reference to nature by writing, "Like a raisin in the sun"(Line 3), I immediately began to think of accomplishments that I had once aspired involving the outdoor life. He then proceeded to take on a new aspect of aiming towards the fact that putting off a dream is similar to failing by writing, "Fester like a sore"(Line 4), which also made me recall the feeling of reminiscing on a forgotten dream as something sad. I enjoyed the middle section that brought up the wonderful portrayal of dreams as a memory to enjoy by comparing it to a sweet that has only gotten better with time.
The conclusion made me wonder how might this authors dreams be holding up. Why end on such a sad note that speaks of dreams holding us back and exploding? I would imagine that this author had to have had a particular inspiration that would make the poem of such wonders end in such an abrupt manner. I still remain in the position that I thoroughly enjoy this poem because of the literary devices used in the similes throughout.
