V. Jeshu ben Pandira I

If we wish, however, to make the distinction quite clearly, we must take into account something else: that is, our dreams. It might be supposed at first that, when the variegated life of dreams works upon us, it consists of concepts continuing their existence into the state of sleep. But, if we test the matter quite accurately, we shall observe that our conceptual life is not continued in our dreams. That which by its very nature wearies us does not continue during our dreams, except when our concepts are associated with intense emotions.
