God speaks once, yea twice, yet Man perceiveth it not, in a Dream, in a Vision of the night, when deep Sleep falleth upon men, in slumbering upon the bed. We need not, when abed, to lie awake to talk with God, he can visit us while we sleep, and cause us then to hear his Voice. Our heart oft-times wakes when we sleep, and God can speak to that, either by words, by proverbs, by signs and similitudes, as well as if one was awake
