The Tragedy of Macbeth — Act 5, Scene 1: Dunsinane. Ante-room in the castle.

At Macbeth’s castle, a Doctor and a waiting-gentlewoman watch Lady Macbeth sleepwalk over two nights and doubt the woman’s strange report until they see it for themselves. Lady Macbeth enters with a candle, still asleep, rubbing her hands as if washing them clean. As the Doctor and gentlewoman observe, she speaks in fragments about blood, guilt, Banquo’s death, and Macduff’s wife, showing that her mind is trapped by remorse. The Doctor concludes that her condition is beyond medicine and that she needs spiritual help instead. He tells the gentlewoman to keep watch over her, then leaves disturbed by what he has seen.
