Thoreau writes in his journal:
carried on conversations which in my waking hours I can neither recall nor appreciate. As if in sleep our individual fell into the infinite mind, and at the moment of awakening we found ourselves on the confines of the latter. On awakening we resume our enterprise, take up our bodies and become limited mind again.
