Hamlet Theme of Appearance vs. Reality

Shakespeare examines the theme of appearance and reality in his book-Hamlet. The dilemma of what is "real" is established at the very beginning of the play. Hamlet doesn't know what to believe and devises a plan to find out. The old king Hamlet appears to be bitten by a snake, but in reality he was poisoned, the ghost appears as an apparition, but it's actually real, and the play-with-in-a-play strongly depicts the theme of appearance vs. reality. The dead King appears to have been bitten by a snake. In reality, he has been poisoned. Everyone believes that the king died from snakebite, but once Hamlet knows the truth he is unsettled by the revelation. When Hamlet's dead father directs his son to, "Avenge him of his foul and most unnatural murder" (1.5. 25), Hamlet's response shows determination to act and a curiosity to know all the facts surrounding the murder: (1.5. 29-31) "Haste me to know't, that I, with wings as swift, as meditation or the thoughts of love may sweep to my revenge." Hamlet's choice of image is significant here. A person who wants to take revenge rarely has "thoughts of love" but only concentrates upon thoughts of revenge, but Hamlet's thirst for revenge is immediate and deep. Shakespeare also develops the theme of appearance vs. reality when Hamlet resents his mother's insinuation that he is putting on a show of being grief-stricken. Strangely, he is the only one in the family who is truly mourning his father's death. He replies that all outwardly signs of his grief, such as his black cloak of mourning, his tears, and his sighs, are mere appearances, not even close to the depth of the real grief in his heart (1.2. 70-80). This theme of appearance vs. reality will play an important part in the entire play.
Another example of appearance vs. reality is the Ghost that appears as an apparition from the depths of hell, when actually he is the medium of reality, revealing the facts to Hamlet. The ghost tells Hamlet that his father was
