Langston hughes - dream deferred ?

if you have time may i suggest reading the play a raisin in the sun which was written based on this poem. it's not very long but explains the poem very well. it's main charachter has a series of dreams that aren't really unatainable but for him, a low cl black man, they are immpossible. Eventually he goes insane, or "explodes", knowing that all the dreams he has been putting off will never really come true.
