What troubled her so, she thinks, is the dream's effect of nullifying the present. For she is passionately attached to her present; nothing in the world would induce her to trade it for the past or the future. That is why she dislikes dreams: they impose an unacceptable equivalence among the various periods of the same life, a leveling contemporaneity of everything a person has ever experienced; they discredit the present by denying it its priviledged status. As in that night's dream: it obliterated a whole chunk of her life; in its place the past came lumbering in.
