For the characters in Of Mice and Men, dreams are useful because they map out the possibilities of human happiness. Just as a map helps a traveler locate himself on the road, dreams help Lennie, George, and the others understand where they are and where they’re going. Many dreams in the work have a physical dimension: Not just wishes to be achieved, they are places to be reached. The fact that George’s ranch, the central dream of the book, is an actual place as opposed to a person or a thing underlines this geographical element. Dreams turn the characters’ otherwise meandering lives into journeys with a purpose, as they take pride in actions that support the achievement of their dreams and reject actions that do not. Having a destination gives the men’s lives meaning. Dreams help the characters feel like more active participants in their own lives because they allow them to believe that the choices they make can have real, tangible benefits. They also help the characters cope with misery and hardship, keeping them from succumbing to the difficulties they face regularly. The dream of the ranch offers George, Lennie, Candy, and the others a goal to work toward as well as the inspiration to keep struggling when things seem grim.
