Answer:
Hallucinations
Inability to sleep.
Explanation:
William Shakespeare's "Macbeth" revolves around the story of Macbeth and his wife's ever-increasing greed for power which led to commit more heinous crimes just to get their desires fulfilled. Aided to their greed is the prophecy of the three witches who foretold that he will become great and be ruler over Scotland.
Both Macbeth and his wife Lady Macbeth have the same attitude or desire to have power. They planned together on how to snatch power and get rid of their enemies, including the king of Scotland, Duncan. And like their support for each other, they also both suffer from the same "repercussions" of their actions. They both were unable to sleep properly after their murderous acts and both have hallucinations (which is also a result of sleep deprivation). Macbeth saw the ghost of Banquo in the feast hall (Act III scene iv) while Lady Macbeth saw blood in her hands (Act V scene i).
