O God, I could be bounded in a nutshell, and count myself a king of infinite space – were it not that I have bad dreams.
– William Shakespeare
Hamlet, Act 2, Scene 2. Hamlet is most comfortable living inside his own head and is a person of thoughts not actions. He says he could live in a nutshell and be king of the universe, but is troubled by bad dreams. This is after his mother’s remarriage and his father’s murder. His bad dreams foreshadow the bad deeds that are yet to come.
