Banquo and his son, Fleance go out for a late night stroll. Banquo first speculates at how the stars are hiding themselves tonight and that he has dreams and nightmares of the weird sisters and cant sleep. Then they come across Macbeth and a servant. Banquo asks about him and he says that he is fine and doesn’t think about the sisters at all (a blatant lie). They exchange somewhat pleasant words and then Banquo and his son finally goes to bed. Macbeth sends the servant away and then stars having hallucinations about a floating dagger that can be seen but not held or touched. He is unsure if it is his eyes that are not working or that his eyes are the only sense that is working. This dagger is leading him towards the kings chamber. A bell is rung by Lady Macbeth and this means that Duncan is unguarded.
“I go, and it is done. The bell invites me. Hear it not, Duncan, for it is a knell that summons thee to heaven or hell.”
