In the times leading up to Duncan’s murder and the moments following, Macbeth displays common characteristics of paranoia. Macbeth’s paranoia plays a major role in the plot of the play and emphasizes the main theme, by suggesting the idea that limitless power can often drive someone insane. Macbeth first shows signs of paranoia in Act II scene i, when he first envisions a dagger that does not exist. This shows how, even though he had already decided that he was to murder Duncan, he was still hesitant; he was already experiencing low levels of guilt mixed with anticipation before the murder was committed. He knows that what he is doing is questionable, but he knows that he will still go through with it because it means that he is going to be king, and in this instance, power outweighs guilt.

The most notable part of his fit, is when he begins to hallucinate Banquo’s ghost. This occurs in Act III scene iv, and Macbeth begins to panic, “Thou canst not say I did it. Never shake thy gory locks at me” (Line 53). Macbeth thinks that everyone can see him and he thinks that Banquo’s spirit is going to tell them all the truth of his actions, but when the others only react to his sudden outburst, his paranoia and panic begin to mix with anger, “If thou canst nod, speak too[...]” (Act III scene iv, Line 72). In this scene as well, Lady Macbeth diverts the people’s attention away from her husband’s obvious display of guilt, and convinces them that he is ill.
