Banquo and his son Fleance walk in the torch-lit hall of Macbeth’s castle. Fleance says that it is after midnight, and his father responds that although he is tired, he wishes to stay awake because his sleep has lately inspired “cursed thoughts”. Macbeth enters, and Banquo is surprised to see him still up. Banquo says that the king is asleep and mentions that he had a dream about the “three weird sisters.” When Banquo suggests that the witches have revealed “some truth” to Macbeth, Macbeth claims that he has not thought of them at all since their encounter in the woods. He and Banquo agree to discuss the witches’ prophecies at a later time.
