Shakespeare creates tension through Dramatic Irony. This is because at the beginning of the play he shows us how the witches are very malevolent as they cursed an innocent woman just beacuse she did not want to give her any of her peanuts. The Witch curses the woman’s husband whom was a sailor, but also curses the rest of the people in the boat. The curse was that the husabnd and the rest of the people in the boat would never go to sleep and would always feel extreamaly hungry. This shows that we can not trust the witches where as Macbeth does not know this at the begginig of the play; he is either extremaly greedy or very naive. This creates dramtic irony as the audience knows that we can not trust the witches where as Macbeth does not this creates tension throughout the play
