" (Act 2, Scene 1, 56-57) The dagger was covered with blood, which represented the bloody course Macbeth was headed down. Once he grabbed the dagger, the wound on the King's body would remain forever, which further illustrated the irrevocable fact that Macbeth wouldn't be able to change his fate, since the murder was the point of no return. From his hallucination of the dagger, we see the inchoate destruction of his conscience, as well as the foreshadowing of chaos and disorder. After committing the murder, the real blood he saw on his hand and the guilt within his mind caused him to experience more hallucinations. "Methought I heard a voice cry, 'Sleep no more! Macbeth does murder sleep,' - the innocent sleep"(Act Two, Scene Two, 43-44) When a person's mind is troubled, sleep becomes impossible and useless. This personification was referring to the fact that King Duncan was killed while he was sleeping peacefully, which left Macbeth tormented and struggled with sleep due to his fear and guilt. "Still it cried, 'Sleep no more!' to all the house. 'Glamis hath murdered sleep, and therefore Cawdor shall sleep no more. Macbeth shall sleep no more.'" (Act Two, Scene Two, 50-52) His hallucinations demonstrated how disturbed he was over the murder. Furthermore, with the switch from Thane of Glamis to Thane of Cawdor in this line, it foreshadowed the worse insomnia that plagued him and his wife later on in this play. If we see the hallucination of the dagger as a sign that revealed the conflict and fear in his mind, at this point his conscience had started to severely corrupt as he was haunted by those imaginary voices spoken in the name of guilt. .
His fear and guilt produced those hallucinations, which then led him to murder more people and virtually expanded his ambition. In order to maintain his power and heal his mental insecurity, he hired murderers to kill his friend Banquo who was believed to be the threat to Macbeth's throne.
