 Studying Macbeth for William Shakespeare. Let's do some word-level analysis on when Macbeth sees the floating dagger before he kills King Duncan. In that two-scene one he asks, is this a dagger which I'll see before me, the handle toward my hand? Now this rhetorical question shows that he's having a hallucination which also represents his feeling of guilt at betraying King Duncan. He says, I have thee not yet I see thee still and the repetition of thee shows that he doesn't hold the dagger but he still imagines and envisions it, showing this is a hallucination. The adjective fatal foreshadows the fatal action he's just about to commit which is kill the king. He asks if the dagger is a dagger of the mind and this is a metaphor to show that he feels a deep sense of guilt at what he's about to do. He says thou marshalts me the way I was going and this is personification basically the dagger is leading the way. He says mine eyes are made full of the other senses and the assolance of O'Hare show that he's being deceived by what he sees. The alliteration of blade and blood show and foreshadow how he's going to kill the king. So Zero here foreshadows his unnatural action.
