Macbeth Analytical Paragraph

The dagger scene in Shakespeare's play "Macbeth" demonstrates how Macbeth's starting to go insane. This is shown by him seeing a dagger that is only visible to him. In 2.1.33-34 it shows Macbeth talking to himself and a dagger. "Is this a dagger which I see before me, the handle toward my? Come, let me clutch thee" he then grabs at the air. By him seeing and attempting to grab a dagger that is not actually there shows that Macbeth is beginning to go insane. Another line that shows that Macbeth is going insane is 2.1.46. "And on thy blade and dudgeon gout of blood" Macbeth still sees the dagger in front of him but now the dagger has blood on it. He tries to tell himself that he's not going insane in  2.1.38-39. He was trying to rub it off as a "false creation, proceeding from the heat-oppressed brain." After talking to himself for a while, Macbeth then says that  it was the murder he was about to commit was the reason he was seeing the dagger. After this conversation Macbeth has with himself it is evident that he is going insane.
