The wonderful Dave Erasmus recently invited me to collaborate with him in a YouTube video, exploring the purpose of sleeptalking and somniloquies, so here’s what we made. On listening to Matt’s night ramblings at first, they seem to be ridiculous, meaningless, and hilarious, just a man lying in bed, unconsciously muttering to himself. If Matt was fully awake when expressing himself in this way, it would be termed a word salad, an attempt to communicate an idea that just emerges in a confused jumble of seemingly random words and phonemes.
