A day without sleep is bad enough with all the headaches and feeling tired. How much more if you haven't slept in weeks or even a whole year. Sleep can be defined as a natural periodic state of rest for the mind and body. In Macbeth, sleep was meant as a sanctuary or a safe haven but as the play progresses sleep becomes fear and not being able to think clearly which gives you a whole different perspective in life.
Sleeping is a way to free your minds and it can make you feel safe, away from all the troubles in your minds. As we sleep we dream, those dreams can represent a persons inner thoughts about what they want and what they need. Our dreams can be like church a place we find comfort in, a place that can feel like home and a place with hope. We can dream about experiences, about doing something so extra-ordinary and about what we want to happen in our lives.
When Macbeth slept, he was harmless, so innocent and so pure, as to anyone you observe when they're sleeping. Sleep can be a place we can take our anger out without hurting anyone. Sleep can also be represented as the core goodness of our hearts, it can be our conscience and/or our values and beliefs. As Macbeth lived in Scotland he believed that in fighting with the Norwegians he was being loyal to his country and his king. As sleep can be our conscience as well, whenever someone does something wrong they tend to have troubles sleeping. Sleep symbolizes what is right and what is wrong, sleep is the bright light that calls upon us to our rooted goodness and to do good.
By sleeping you dream and in those dreams...
