Macbeth and Lady Macbeth both have 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 where he commits numerous murders due to his ambition. Macbeth's hallucinations reflect his mental state. Throughout the play, Macbeth slowly loses his sanity. Macbeth's visions and the witches' prophecies lead Macbeth to make poor decisions that lead to his final downfall. Macbeth started out as a noble and virtuous man, he was loyal to the king and was highly respected by the other nobles. The prophecies and hallucinations corrupt Macbeth's intentions, and as a result, Macbeth becomes powerful. A combination of Macbeth's ambition and paranoia leads 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 itself in the ghost. Macbeth says he feels guilty because of the murders. “Yes, and since then murders too terrible to hear have been committed.” (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. Furthermore, after Duncan's murder, Macbeth is filled with regret and guilt. The voices he hears reflect his mental state. “I thought I heard a voice shouting: “Don't sleep anymore!” (II, ii, 35) His innocence has been killed and he knows that he will have to live with this guilt for the rest of his life, so Macbeth will never sleep peacefully again. After each subsequent murder, Macbeth becomes more and more inhuman. "I am in the blood, I have entered so far that, if I were to wade no more, the return would be as tedious as the going further." (III, iv, 143-145) Macbeth claims that after committing murder there is no turning back. He killed his best friend because of his ambition and fear. The third murder was completely moralless and unnecessary. He compulsively killed Macduff's wife and children. Macbeth shows no remorse for his murders, he becomes an absolute monster towards the end of the play. As Macbeth loses his human morals, the hallucinations seem to remind him of the sins he has committed
