Since his Majesty went into the field I have seen her rise from her bed...take forth paper, fold it, write upon't, read it, afterwards seal it and again return to bed; yet all this while in a most fast sleep.
That, sir, which I will not report after her...having no witness to confirm my speech.
What at any time have you heard her say?
Two nights I have watched with you but can perceive no truth in your report.
Lo you, here she comes.
She has light by her continually. 'Tis her command.
I have known her continue in this a quarter of an hour.
Out damned spot, out I say!...What need we fear who knows it when none can call our power to account?
A doctor and gentlewoman who waits on Lady Macbeth discuss Lady Macbeth's recent behaviour, commenting on her sleepwalking.
She spoke what she should not, I am sure of that. Heaven knows what she has known.
The Thane of Fife had a wife. Where is she now? What, will these hands ne'er be clean?
Lady Macbeth enters, holding a taper. Her eyes are open, but do not register anything.
Wash your hands. Put on your nightgown. Look not so pale. I tell you yet again, Banquo's buried; he cannot come out on 's grave.
To bed, to bed...Give me your hand. What's done cannot be undone. To bed, to bed, to bed.
Lady Macbeth starts rubbing her hands, as if washing them.
Foul whisp'rings are abroad. Unnatural deeds do breed unnatural troubles. Infected mind to their deaf pillows will discharge their secrets. More needs she the divine than the physician. God, God forgive us all!
Lady Macbeth reveals how she has participated in murdering others, such as Lady Macduff (the wife of the Thane of Fife).
Lady Macbeth refers to Banquo's murder, and how nothing can be done about the crimes committed. She then goes to bed.
After Lady Macbeth has gone to bed, the doctor tells the gentlewoman how Lady Macbeth needs help mentally, marvelling at her madness.
