[126] And this dream, to speak the truth, is the life of man; for as in the visions which appear to us in sleep, which seeing we do not see, and hearing we do not hear, and tasting and touching we do not either taste or touch, and speaking we do not speak, and walking we do not walk, and while appearing to exert other motions or to win other positions we are not in reality in any such motions or positions; but they are mere empty fancies without any truth in them of the mind which fancies to itself a sketch, and makes to itself a representation of things which are not, as if they were; and in like manner the fancies which occur to waking people resemble the dreams of sleepers. They have come, they have departed; they have appeared, they have disappeared; before they could be scarcely comprehended they have flown away.
