Macbeth takes place in a world where supernatural characters from witches to ghosts are present. In Shakespeare's Macbeth, the supernatural plays an important role in motivating Macbeth’s actions. This can be seen during his first encounter with the witches, him seeing Banquo’s ghost, and him seeing the three apparitions.
The first encounter Macbeth has with a supernatural being is when he and Duncan run into the three witches while they are walking. During this encounter with the witches, the first witch says to Macbeth, “All hail, Macbeth! Hail to thee, Thane of Glamis!” (1.3), the second witch says “All hail, Macbeth! Hail to thee, Thane of Cawdor!” (1.3) and the last witch says to him “All hail, Macbeth, that shalt be king hereafter!” (1.3).
