Has Macbeth gone mad in Act 2 Scene 1?

            Macbeth has gone mad in Act 2 Scene 1 because he is anxious about murdering King Duncan. Macbeth is hallucinating that there is dagger in front of him. He says, “Is this a dagger which I see before me/ The handle toward my hand?” (2.1.33-34). By this, Macbeth means he is unsure of whether or not the dagger is actually there. At this point it seems that Macbeth is going mad to the point of having multiple personalities. This may be true because Macbeth’s character in the beginning of the play was a valiant, noble man serving his king to and has changed to an easily manipulated, soon to be murderer. Macbeth’s delusions about the dagger prove that he has gone mad. He says, “A dagger of the mind, a false creation/ Proceeding from the heat-oppressed brain?” (2.1.38-39). When Macbeth says this he is telling himself that he is crazy for wanting to kill the king and admitting that he is not well in the head. Therefore, Macbeth has gone mad in Act 2 Scene 1.
