Macbeth’s visions and hallucinations are an important role to the development of his character. Macbeth is convinced to murder his king and his friends after given a prophecy said by the witches. Even though the witches set off events that later help Macbeth drop into insanity, Macbeth is described from the beginning as a strong and loyal man. As the play goes on, several problems inside of Macbeth become clear to the audience of the play and as well as the people around him. After he performs several murders, the insanity inside of Macbeth is visible to everyone around him. Tt shows his guilt in all of the events that have happened with Macbeth. Macbeth’s visions and hallucinations play a role in the development of his character by his insanity after seeing the ghost of Banquo, the bloody dagger, and the apparitions.One of the most important hallucinations or visions that happen in the play Macbeth is the floating bloody dagger, which follows Macbeth as he goes to murder Duncan. When Macbeth envisions the dagger he says, “Is this a dagger which I see before me?” (2.1.44). Macbeth does not believe that the bloody dagger is real, since he can’t touch it, but is visible. Macbeth even says to himself himself that it might be an hallucination. Macbeth notices that the bloody dagger is not real. This was one of his signs into insanity.Later in the play, Macbeth sees the ghost of Banquo sitting at the table during the Banquet. Macbeth is paranoid and nervous that Banquo will be found sitting at the table. The hallucination of Banquo’s ghost reminds him that he has killed a close friend and reminding him of his guilt. During the banquet as Macbeth sees the ghost he says to Banquo, “Thou canst not say I did it. Never shake/Thy gory locks at me” (3.4.61-62). This is important because it represents Macbeth’s guilt which shows the development of his character. Now, he is able of killing his friend without blinking an eye and this is clear sign of corrupted and evil soul. Macbeth is clearly losing his mind and showing development towards being because of his guilt, he plans to go see the witches once again. Macbeth decides to go to the witches and experience his third hallucination. The witches summon the four apparitions that tells his fate in an indefinite matter. One of the apparitions tells him, “Macbeth shall never be vanquished by until/Great Birnam wood to high Dunsinane Hill/Shall come against him” (4.1.105-107). After having these visions, Macbeth becomes sure of what he needs to do. He decides he must kill Macduff and his whole family. This shows Macbeth’s insanity, he is now set on killing children and women because of an apparition that may or may not have been real. In conclusion, Macbeth’s hallucinations and visions play a significant role in the development of his character. It is important to know that his hallucinations and visions did not cause his insanity. His insanity caused his visions and hallucinations. Macbeth’s wife did nothing to help stop what he was going through and just let his the problem develop. It is possible that Macbeth would not do all the things he did if Lady Macbeth did not insist, pushed and pressured him into doing such actions. Lady Macbeth knew his goals and personality and it was possible for her to say something before Macbeth deciding to murder. From the beginning of the play to the end, Macbeth developed from a fierce and loyal person to someone with evilness, suspicion and guilt.
