In Act 3, What is Asagai's dream in A Raisin in the Sun?

Asagai dreams of returning to his village and making
positive changes. He admits that this will be difficult initially, because at first what
he has to tell them will not make sense, or will be strange in terms of their
traditions. This comes in the form of a scolding of Beneatha, as she has dropped into a
sort of depression about the state of the human condition. He chides her for losing her
idealism and drive to help people, and invites her to come with him to Africa to help
make changes.
