Lady Macbeth is aware of this and tells Macbeth saying, “You lack the season of all natures, sleep” (III, iv, 167). Through losing his ability to sleep Macbeth creates a great amount of disorder in his life and the lives of his countrymen. * Fearful of the vulnerability it creates, Banquo refuses to allow himself to sleep. Confiding in his young son Banquo shares, “A heavy summons lies like lead upon me, and yet I would not sleep” (II, i, 7-8). Having been in combat along side Macbeth just a day or two before, it is only natural for Banquo to be exhausted and desiring sleep. However, he recognizes that Duncan was killed so easily, because it was done at a time when he left himself susceptible to all attackers. He fears that Macbeth will inevitably take his life, and reasons that he must remain awake to maintain constant self-defense. * The inner voice of Macbeth’s conscience shows Macbeth’s inability to sleep is simply due to bad karma.
“Still it cried ‘sleep no more! To all the house: ‘ Glamis hath murdered sleep, and therefore Cawdor shall sleep no more: Macbeth shall sleep no more!’” (II, ii, 53 – 55). Through his act of taking the life of an innocent man, at a time when he stood no chance at defending himself, Macbeth murders innocent sleep. Murdering this innocent sleep leads Macbeth into a cursed life where he is no longer able to enjoy a good night’s sleep. Without proper rest, Macbeth begins to take actions without first thinking them through. In doing this Macbeth makes it clear that he has murdered Duncan. These careless actions will set in motion the downfall of
Macbeth. * Having already killed Duncan, Macbeth begins to view sleep as a time when one is made vulnerable to the evilness of bad dreams. As Macbeth finishes a conversation with the fearful Banquo, he tells the audience, “ Now o’er the one half – world nature seems dead, and wicked dreams abuse the curtained sleep” (II, i, 5y – 59). Macbeth tells us that he understands that he has deceived a great deal of people, and that they are metaphorically trapped in a nightmare in which nothing is true. Blinded by this dream, the people of Scotland are unable to discover the terrible actions that Macbeth has committed. Through his triumph over Macbeth, Malcom ultimately serves to wake Scotland of the nightmare they have been tricked into, and brings his people back to a state of reality. * Lack of sleep sends Macbeth down a path full of deranged thoughts and bad choices. Losing his ability sleep, Macbeth becomes unable to regain his sanity, and ultimately dies because of it. This is the result of a principle that always been known to man, sleep is a necessary part of a fully functioning life. *
