I dreamt last night of the three Weïrd Sisters.To you they have showed some truth.
If you shall cleave to my consent, when ’tis,It shall make honor for you.
So I lose none in seeking to augment it,but still keepMy bosom franchised and allegiance clear,I shallbe counselled.
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” (2.1.8). Macbeth enters, and Banquo is surprised to see him still up.
Is this a dagger which I see before me,The handle toward my hand? Come, let me clutch thee.
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
I have thee not, and yet I see thee still.Art thou not, fatal vision, sensible,To feeling as to sight?
Macbeth is telling Banquo, If you stick with me, when the time comes, there will be something in it for you." He wants Banquo to trust him and be on his side.
I go, and it is done. The bell invites me. Hear it not, Duncan, for it is a knell
Banquo and Fleance leave, and suddenly, in the darkened hall, Macbeth has a vision of a dagger floating in the air before him, its handle pointing toward his hand and its tip aiming him toward Duncan.
He wonders whether what he sees is real or a “dagger of the mind, a false creation / Proceeding from the heat-oppressed brain”.
A bell tolls—Lady Macbeth’s signal that the chamberlains are asleep—and Macbeth strides toward Duncan’s chamber.
