The correct literary device wold be metaphor
At Forres, Macbeth and his wife welcome the thanes of Scotland to the banquet. Immediately prior to the feast, one of the murderers appears at a side door and reveals to Macbeth the truth about the mission: their success in the killing of Banquo and their failure to murder Fleance. Macbeth recomposes himself and returns to the table. As he raises a toast to his absent friend, he imagines he sees the ghost of Banquo. As with the ethereal dagger, the ghost of Banquo appears to come and go, propelling Macbeth into alternating fits of courage and despair. Lady Macbeth invites the thanes to depart and, once alone, tries one last time to soothe her husband. But Macbeth's paranoid mind is already on to the next murder, that of Macduff. To ascertain his future with greater certainty, he makes clear his intention to visit the Weird Sisters once more.
