In the Farrelly Brothers', Dumb and Dumber, Jim Carey plays the character, Lloyd Christmas whose role is entirely driven to end up with his love, Mary Swanson. Christmas shows how every decision he makes is influenced by Love, Acceptance, and a hint of Sex. He travels from Rhode Island to Aspen, Colorado to return Mary's suitcase back to her, hoping she will then fall in love with him. Sigmond Freud's theory of the unconscious mind is applicable here because Lloyd Christmas almost acts as one's unconscious mind himself. Freud explains how one should not necessarily be in touch with their unconscious mind because it is often too frightening or painful. In my opinion, Lloyd is that scary part due to his obsessive behavior for Mary, and also because he is one of the weirdest humans you'll ever meet.
