"And from hence also it is evident that Dreams are sometimes to be call'd, and really are, Apparitions, as much as those other visible Apparitions which are seen when we are (as we call it) broad awake; that Apparition is to the Eyes of the Soul, and as it is so, it may be seen as well sleeping as waking, for the Imagination sleeps not."
— Defoe, Daniel (1660?-1731)
