Freud's masterwork, The Interpretation of Dreams, cites examples from Hamlet, Henry IV Part 1 and Part 2, Henry VI Part 3, Julius Caesar, King Lear, Macbeth, A Midsummer Night's Dream, Othello, Romeo and Juliet, and Timon of Athens. In his letters Freud compares himself to Hamlet and his beloved daughter Sophie to Lear's daughter Cordelia.
