[General] Rhetorical questions

[angelsrolls]

I heard an English-speaking person say to herself "what nonsense I am talking?" This certainly is not a question, but an incomplete sentence. Is it something to do with it being a rhetorical question?

If they definitely said "What nonsense I am talking!", it was an exclamation, not a question of any kind. Even a rhetorical question would take the word order "What nonsense am I talking?"
