This case of sleep walking, if we consider it, seems first to correspond entirely to the popular view, that the wanderer carries over to the nighttime the activities of the day, or to speak more correctly, of the most important day of the last month. We saw in the first act how she reproaches Macbeth for his cowardice, encourages him and controls his actions. Only in two points, very significant ones to be sure, does it appear that she has now taken over her husband's rôle upon herself; in the disturbance of her sleep and the concern for the blood upon her hands. How had she rebuffed Macbeth when he had called out in regard to his bloody hands, "This is a sorry sight!" It was only a foolish thought. "Go get some water, And wash this filthy witness from your hand." But Macbeth was not to be shaken, the entire ocean would not suffice. Rather would the king's blood, which he had shed, change its green to glowing red. Yet when Lady Macbeth completes his work for him, she remarks lightly, "My hands are of your color; but I shame To wear a heart so white.... A little water clears us of this deed." In her sleep walking itself she encourages her husband, "Wash your hands, put on your nightgown." She seeks however in vain in this very sleep walking to wipe the stains from her hands, they smell always of blood and not all the perfumes of Arabia will sweeten her hands. Must not the inner meaning of all her sleep walking lie exactly in these two points, in which she has so completely turned about? It must be observed that in the tragedy as in the previously related tale of the "Sin Child" the sleep walking does not begin in childhood nor in puberty, but in both instances in somewhat more mature years, and, what is significant, as an illness, more precisely a psychic illness. The sin child fell ill because he had lost his pure beloved one, who had taken the place of his mother, the original love object of his earliest childhood; and Lady Macbeth, who had herself become queen through a murder, falls ill just at that moment when her lord must go to the battlefield to defend his life and his crown. For not without reason the fate of Macduff's wife, who was slain when her husband had gone from her, occurs to her also when she, while wandering, speaks of the much blood which Duncan had. Therefore it seems likely, and is in fact generally believed, that Lady Macbeth becomes ill because of her anxiety for life and kingdom. Only the facts do not strictly agree with this. In the first place her husband's campaign is by no means unpromising. On the contrary he has heard from the witches that his end would be bound with apparently unfulfillable conditions, so unfulfillable that the prophecy at once frees him from all fear.
