What happens to a dream deferred?

What happens to a dream deferred?

     Does it dry up
     like a raisin in the sun?
     Or fester like a sore-
     And then run?
     Does it stink like rotten meat?
     Or crust and sugar over-
     like a syrupy sweet?

     Maybe it just sags 
     like a heavy load.

     Or does it explode?
