The thoughts that jostle in the noisy mind are often propositional fragments, that is, inner speech or otherwise directed significations. As far as the speaking part of this is concerned you do not do this so as to listen to your thoughts but to utter them as if to another, they are utterances rather than voices. As such they have an addressee, and while this might be 'yourself', as when you are trying to shape an idea, but more often than not they are specific others, either ones you know of or vague remembered faces in a nebulous mist. So, you could say that what floats up into the distracted, default mode, mind are disembodied others, a crowd of faces out of a personal cinema. The hint of an identity being enough to trigger an utterance. Other phases of mental noise may be more specifically addressed to you, but these are not utterances, not sub=vocal speech, but feelings and emotions that are triggered by other elements in the phantasmagoria. The default mode is thus a low level prosopopeia in a swirl of fragments out of time and out of space.
