What is the “vision” Macbeth sees before him? Outline in your own words the thoughts that fill Macbeth’s mind.

Before Macbeth, the "vision" he sees is a dagger. This is a hallucination that appears to him, leading him towards Duncan's chamber where he plans to commit the murder. The dagger is covered in blood and points him in the direction of the king's room. This vision is a manifestation of Macbeth's guilt and ambition, symbolizing the violent path he has chosen to take to achieve his goals.

Macbeth's mind is filled with conflicting thoughts and emotions. On one hand, he is driven by his ambition to become king, a goal that he believes can only be achieved by murdering Duncan. On the other hand, he is plagued by guilt and fear about the act he is about to commit. He is aware of the moral and societal implications of his actions, and this awareness fills him with dread. He is also fearful of the consequences, both earthly and divine, that he might face for his crime. Despite these fears, his ambition ultimately overpowers his guilt and he proceeds with the murder.
