This document summarizes the use of supernatural elements in two of Shakespeare's tragedies, Hamlet and Macbeth. It notes that Shakespeare incorporated strong beliefs in the supernatural that were common during the Elizabethan era, such as witches, ghosts, and spirits. Specifically, it discusses how the ghost of Hamlet's father drives the plot and themes of revenge and internal conflict in Hamlet. Meanwhile, Macbeth features the apparitions of witches, a floating dagger, and Banquo's ghost, all of which influence Macbeth's ambitions and actions. The supernatural elements were an integral part of Shakespeare's plays and helped captivate audiences by seeming plausible within the time period.
