A major theme within Macbeth is that the characters experience paranoia when they have committed a guilty action. A clear example of this is when Macbeth sees Banquo's ghost immediately after hearing the news that his plan to kill Banquo was a success. When he first sees the ghost he says, “You can't say I did it. Never wave your bloody locks at me.”(3.4.61-2) These lines show Macbeth's paranoia regarding the topic of Banquo's death. When he says these lines, he is in a room full of people and he seems a little crazy because they think he is the one talking or seeing things, which in fact he is. This example shows that Macbeth is so paranoid that he imagines things in his head. This shows that he is terrified of what would happen if the truth came out
