Wikipedia on dialogue in theatre of the absurd: “repetitive or nonsensical dialogue and dramatic non-sequiturs are often used to create dream-like, or even nightmare-like moods.”

For example:

XX: I think that you people are under a curse.
[…]
AA: I like what you said just now.
XX: Do you?
AA: The great problem is to understand thoroughly the nature of the curse.
XX: That’s not very difficult, I think.
AA: I think so too.
XX: A curse is an evil spell and the important, the great problem, is to find the means to break it.
AA: Yes. To find the means.

Beckett? Ionesco? Genet? No, it’s Joseph Conrad in Under Western Eyes, beating the absurdists by nearly half a century.
