Macbeth Act 2, Scene 1

At then end of this scene, Macbeth is just starting to get up the courage to follow through with the murder. He may be going a little insane, probably from a guilty conscience. Macbeth starts to hallucinate about a bloody dagger. However, this does not seem to change his mind about the murder. His only hope is that everything will go as planned and Duncan will not wake up before Macbeth can do the deed.
