To me there seems to be a big clue in the phrase " there's a bodgens at the door, should I garest him?" I think there's something behind the speaking/communication disorder tied with the statement that nobody understands her. The door phrase could have easily meant "there's a banging at the door, should i greet him?" .
Everything else that is said is very cryptic with the exception of the door phrase and the statement that nobody understands her. There might be a reason these were purposefully left fairly simple and straightforward albeit random. So the question remains if every other word or jumbled phrase that is in the monologue stands for another word that might be close does the word need to be similar in sound or just start with the same letter?
