Assumptions are made throughout our lives, just as the nobles suspect Macbeth of murder. Macbeth has given them a reasonable amount of examples to justify their predictions of his bloody doings, yet his inner monologue is available only to the reader. Such thoughts of his guilt and remorse are expressed through his discussions with Lady Macbeth, his unconscious reactions to Banquo's ghost and the "tomorrow and tomorrow" speech. Scotland makes accusations through Banquo's soliloquy and the nobles speaking of Macbeth in act five proving their beliefs of murder. The entire country believes he is covered in blood yet the reader is the only one who understands his reactions towards the deeds he has committed.
Like a child, Macbeth attempts to run away from his problems, yet he has no where to go. "I am afraid to think what I have done", reveals his inability to think over scenarios before he commits them. He now realizes what he has done is against his own morals, knee deep in guilt, and attempts to figure out his problems with his wife. Macbeth "s conscious screams through, "Ere we will eat our meal I fear and sleep in the affliction of these terrible dreams that shake us nightly", for the reality of the crime has come into realization and the only one Macbeth can confide in is Lady Macbeth. At this point in the book, no guilt is felt on behalf of Lady Macbeth leaving Macbeth resembling a boy crying for help when no one is listening.
Through Macbeth's attempt to make sense of what has happened during the "tomorrow and tomorrow" speech, he states, "Life's but a waking shadow, a poor player that struts and frets his hour upon the stage and then is heard no more". He claims we will all, at some point in our lives, end up having to finish our play, though when that happens it makes no difference, for our lives "signify nothing." By claiming life is insignificant, Macbeth makes excuses for the murders he has committed, yet deep down inside this is simply a cover-up for the guilt boiling inside.
