Answer:
Step-by-step explanation:
Before Macbeth murders Duncan, he sees a vision of a floating dagger. The dagger appears before him, leading him towards Duncan's chamber. However, Macbeth realizes that the dagger is merely a hallucination, a product of his own troubled mind. The vision of the dagger symbolizes Macbeth's internal conflict and his wavering determination to carry out the heinous act. It represents his deepening descent into darkness and his struggle with guilt and moral conscience. The sight of the dagger further fuels Macbeth's ambition and propels him towards committing the regicidal act. It serves as a haunting reminder of the evil deeds he is about to undertake and foreshadows the psychological torment and consequences that will follow.
