that something falls off during sleep, which, having the effect of an inhibition, has kept us from noticing the existence of such an impulse. The dream thus shows the real, if not the entire nature of man, and is a means of making the hidden psychic life accessible to our understanding. It is only on such assumption that Hildebrandt can attribute to the dream the rôle of monitor who calls our attention to the moral ravages in the soul, just as in the opinion of physicians it can announce a hitherto unobserved physical ailment. Spitta,64 too, cannot be guided by any other conception when he refers to the stream of excitement which, e.g., flows in upon the psyche during puberty, and consoles the dreamer by saying that he has done everything in his power when he has led a strictly virtuous life during his waking state, when he has made an effort to suppress the sinful thoughts as often as they arise, and has kept them from maturing and becoming actions. According to this conception, we might designate the "undesirable" presentations as those that are "suppressed" during the day, and must recognise in their appearance a real psychic phenomenon.
If we followed other authors we would have no right to the last inference. For Jessen36 the undesirable presentations in the dream as in the waking state, in fever and other deliria, merely have "the character of a voluntary activity put to rest and a somewhat mechanical process of pictures and presentations produced by inner impulses" (p. 360). An immoral dream proves nothing for the psychic life of the dreamer except that he has in some way become cognizant of the ideas in question; it is surely not a psychic impulse of his own. Another author, Maury,48 makes us question whether he, too, does not attribute to the dream state the capacity for dividing the psychic activity into its components instead of destroying it aimlessly. He speaks as follows about dreams in which one goes beyond the bounds of morality: "Ce sont nos penchants qui parlent et qui nous font agir, sans que la conscience nous retienne, bien que parfoit eile nous avertisse. J'ai mes défauts et mes penchants vicieux; a l'état de veille, je tache de lutter contre eux, et il m'arrive assez souvent de n'y pas succomber. Mais dans mes songes j'y succombe toujours ou pour mieux dire j'agis, par leur impulsion, sans crainte et sans remords.... Evidement les visions qui se déroulent devant ma pensée et
