What are the two stanzas in dream by Langston?

You're likely referring to the poem "Dream Deferred" by Langston Hughes, not "Dream" by Langston. There are four stanzas in "Dream Deferred", not two. Here they are:

Stanza 1:

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?

Stanza 2:

Maybe it just sags

like a heavy load.

Or does it explode?

Stanza 3:

I have a dream.

I have a dream.

I have a dream.

Stanza 4:

I have a dream

of freedom.

I have a dream

of peace.

I have a dream

of equality.

This poem is a powerful reflection on the struggles and aspirations of African Americans in the 1950s and beyond. The first three stanzas explore the potentially devastating effects of delayed dreams, while the fourth stanza reveals the poet's own enduring hopes for a better future.
