Macbeth and Lady Macbeth both have very impactful hallucinations that change the course of their destinies. The first encounter with the witches reveals Macbeth's ambitious nature. The prophecy of becoming king leads Macbeth down a bloody path in which he commits many murders out of ambition. Macbeth's hallucinations reflect his mental state. Throughout the play, Macbeth slowly loses his mind. Macbeth's visions and the witches' prophecies cause Macbeth to make bad decisions that ultimately lead to his downfall. Macbeth started out as a noble and virtuous man, he was loyal to the king and well respected by the other nobles. Prophecies and hallucinations corrupted Macbeth's intentions and as a result, Macbeth rose to power. A combination of Macbeth's ambition and paranoia led to many senseless murders. He killed his best friend Banquo out of fear and senselessly murdered Macduff's family. The hallucination of Banquo's ghost is a representation of Macbeth's guilt, all of Macbeth's guilt manifests in the ghost. Macbeth states that he feels guilty because of the murders. “Yes, and since then too, murders have been committed, too terrible for the ear.” (III, iv, 80-81) Seeing Banquo's ghost is the breaking point for Macbeth. The ghost also causes him to think more irrationally, which leads to Macduff's murder. Additionally, after Duncan's murder, Macbeth is full of regret and guilt. The voices he hears reflect his mental state. “I seemed to hear a voice shouting: “Sleep no more! » (II, ii, 35) His innocence has been killed and he knows he must live with this guilt for the rest of his life, which is why Macbeth will never sleep peacefully again. After each successive murder, Macbeth becomes more and more inhuman. "I am in the blood. I have gone so far that, if I waded no more, the return would be as tedious as leaving." (III, iv, 143-145) Macbeth states that after committing a murder, there is no turning back. He killed his best friend because of his ambition and fear. The third murder was downright moralless and unnecessary: ​​he compulsively killed Macduff's wife and children. Macbeth shows no remorse in his murders, he becomes an absolute monster towards the end of the play. As Macbeth loses his human morale, hallucinations seem to remind him of the sins he has committed.
