This scene shows Lady Macbeth break down. A doctor and a gentle waiting lady are present with her in a room in the castle trying to figure out what is wrong with her. The waiting woman says she has not really woken. As they are observing her sleepwalking she looks as if she is washing her hands. Then she speaks but she speaks nonsense. Finally the Doctor says that the ‘condition’ she has is beyond his practice. After this Lady Macbeth starts telling them they need to go to bed.
“Yet there is a spot”
“Out, damned spot! Out I say! – One; two; why, then’t is time to do’t – Hell is murky. … Yet who would have thought the old man to have so much blood in him?”
“More she needs the divine than the physician…”
“To bed, to bed: there is a knocking at the gate. Come, come, come, come, give me your hand. What’s done cannot be undone.”
