Shakespeare's Macbeth is a play that holds many supernatural elements, such as the three witches, the levitating dagger, and the Ghost of Banquo. Throughout the whole play these three examples all play a major role in the outcome of the play.
These three evil witches, who were also known as "the weird sisters , played a pivotal role in the play. All they wanted was to stir up trouble in any way they could. They have power and magic, which they can use to disrupt anyone they wishes lives. They arrange to meet with Macbeth so they can put thoughts of murder into his head by chanting strange prophecies. Macbeth is deeply frightened by the witches and their prophecies and eventually starts to believe them and thinks that the only choice he has is to follow what they say for the prophecies will all come true somehow no matter what happens. Though we, the audience, know that the witches are only trying to stir up trouble with no real goal or purpose at hand, Macbeth falsely believes their magic and malice are sending him a secret message of the mission he must fulfill. The witches are important to the play because though not literally, they are the ones who put the idea of murder and deceit into Macbeths head which began the murderous and tragic events, which followed thereafter.
The dagger that was used to kill Duncan and Banquo also seemed to take on some supernatural characteristics.
Macbeths state banquet starts off with the formality it deserves but things are disrupted when the Ghost of Banquo makes an appearance. Macbeth is the only person who can actually see the Ghost. When Macbeth sees the Ghost he is so frightened that he loses control and begins to act very strangely. Since Macbeth is the only one who is able to see the Ghost, all the other attendants as well as Lady Macbeth are completely confused and dumbfounded by Macbeths odd behaviour.
