Demetrius’s Dream One of Shakespeare’s major theme in A Midsummer Night’s Dream is the analogy that love is like being in a dream; mystical‚ unexplainable and changeable.

Through the usage of unique language and context Shakespeare is able to penetrate the imagery of Demetrious’s love to enforce this theme throughout
