I have been thinking "cursed thoughts" about the prophecies...
We'll talk about it later, Banquo.
"Don't think about it so much."
"Methought I heard a voice cry, 'Sleep no more! Macbeth is murdering sleep.'"
In this scene, Banquo and Macbeth are conversing about the prophecies. Banquo is still confused and trying to figure out what the prophecies had said, while Macbeth acts like he hasn't put much thought to it. Macbeth offers to talk about it another time.
Here we see an apparition taking place. Macbeth has plans of killing Duncan, and as fate has it, Macbeth sees a bloody dagger pointing towards Duncan's room. This leads to the event of the killing of Duncan.
We need to flee, we are in danger.
Woe, alas! What, in our house?
Shown above is the moment after the killing of Duncan, when Macbeth met Lady Macbeth in their room. Macbeth is covered in blood and is holding the weapons he used to kill Duncan. Macbeth is flustered after performing murder, while Lady Macbeth is telling him to not think that way, and she then leaves to wipe the blood on the guards in order to frame them for the murder.
What a strange, unnatural night...
Depicted is Lady Macbeth following through with her plan of framing the guards for the murder by wiping the blood of Duncan on them. After they had been drinking all night, they are passed out on the floor, unconscious.
Here is the scene where Macduff and Lennox found out about King Duncan's death. After arriving at Macbeth's castle to get the king, Macduff went to wake him up, finding him dead. He delivers the news to everyone, and Lennox comes to the conclusion that it was the guards. Some notice that the king's sons had a suspicious reaction of wanting to flee the country instead of showing grief for their father.
King Duncan is dead...
Above is the scene where Ross and an old man are talking about the mysterious and unnatural events that have been occurring. These events include the days being as dark as nights, owls hunting falcons, and Duncan's horses going mad and eating each other. Macduff then appears and announces that the bodyguards killed the king, the suspicion towards the brothers due to flight, and that Macbeth has been made king.
