 Let's discuss how Lady Macbeth responds to Macbeth who's hallucinating and seeing Banco's ghost. Lady Macbeth is exasperated when she sees Macbeth's terror. She says, Oh, proper stuff. And this exclamatory sentence shows just how dismissive she is of what he is hallucinating. In contrast to Macbeth, she seems really, really calm and collected. She speaks in iambic pentameter. Here we can see that in contrast to Macbeth who's terrified of being found out that he killed Banco, Lady Macbeth can care less. Lady Macbeth also reminds him of the dagger he saw, the air-drawn dagger. And as we can see here, she's really dismissive of Macbeth's own fears. She refers to the vision of the dagger but also Banco's ghost as imposters. Now this is a metaphor where she's basically dismissing Macbeth's fears as almost childish imaginings. The Caesarea here, after she talks about it being almost like a story, shows her utter disgust at Macbeth. Also, this rhetorical question shows she's asking him to be a man to get a hold of himself.
