Lady Macbeth says that the ghost of Banquo is of the same nature as the dagger Macbeth saw leading him to Duncan. How does she characterize Macbeth's weakness in this regard? How does she seek to push him from it?

I'm having a very hard time with this question, for anyone who has read Macbeth, please help me out.
It'd be much appreciated.
Thank you.

In this scene, Lady Macbeth is trying to convince Macbeth to regain his composure and move on from his guilty conscience. She compares the ghost of Banquo to the imaginary dagger that Macbeth saw before Duncan's murder, suggesting that they are both creations of his own mind. Lady Macbeth characterizes Macbeth's weakness as his susceptibility to illusions and hallucinations, which arise from his troubled conscience.

To push Macbeth from this weakness, Lady Macbeth employs several strategies. First, she questions his manhood and bravery, implying that a strong and courageous man would not be haunted by illusions. By attacking his masculinity, she hopes to shame him into suppressing his guilt and regaining control over his thoughts and actions.

Furthermore, Lady Macbeth advises Macbeth to adopt a pragmatic approach to dealing with guilt and fear. She reminds him that the ghost is merely a creation of his imagination and cannot physically harm him. She encourages him to confront his fears and doubts with rationality, urging him to not give in to paranoia or irrational behavior.

It is important to note that Lady Macbeth's efforts to push Macbeth from his weakness ultimately contribute to his downfall. Her constant urging for him to suppress his guilt and act without remorse drives him to commit more crimes, leading to his unraveling and demise.
