Apart from the foreboding night and the meaning behind that dreary setting, the reader must notice the almost immediate entrance of the ghost in the very first scene of Shakespeare's play. For a moment, leave aside the questions about why the ghost has appeared. (In reality, that is a very important topic that will be dealt with in later insights.) Simply the appearance of the supernatural, something that only some people believe in, already calls up a common theme: Appearance versus Reality. Is the ghost real? Are the men tired and lonely and seeing things? Is it a figment of their imagination? Could a ghost actually exist? Thus begins a journey through this theme that will last the entire length of the play.
