Explanation:

Macbeth is the story of a nobleman from Scotland by name Macbeth who plots (with his wife) to eliminate their king (King Duncan) to fulfill their desire for Macbeth to be king.

The story also captures the repercussions that follow.      

After the demise of Duncan and his family (save those that escaped) by Macbeth, Lady Macbeth becomes stricken with a heavy heart. Unable to sleep properly due to the guilt of how she and her husband ascended the throne, she starts sleepwalking while confessing indirectly to her evil deeds.

Between lines 30 and 50, the doctor observes this along with another lady. He understands that her mind is troubled. Between lines 50 and 55, the Doctor alludes to the fact that her problem is unnatural and that the cause is as a result of unnatural deeds.  

It was unnatural for Macbeth to slay Duncan and his family just because of power. Unnaturally, Lady Macbeth also killed herself.

Cheers!
