Summary: Act 5, scene 1
At night, in the king’s palace at Dunsinane, a doctor and a gentlewoman discuss Lady Macbeth’s strange habit of sleepwalking. Suddenly, Lady Macbeth enters in a trance with a candle in her hand. Bemoaning the murders of Lady Macduff and Banquo, she seems to see blood on her hands and claims that nothing will ever wash it off. She leaves, and the doctor and gentlewoman marvel at her descent into madness.

The “tyrant,” as Lennox and the other lords call Macbeth, has fortified Dunsinane Castle and is making his military preparations in a mad rage.
