It helps one to be many people, to do those things which could never be done. It is often a subconscious reaction to the events of the day. These reactions usually come out at night and are called dreams. Imagination inspires great writers and painters. Many of the world's greatest works of art and literature would never exist if not for imagination.
Imagination often leads one to romanticism.
Many young girls romanticize about the ideal man. They know that they may never meet him, yet they think about being married to such a man. Boys are not immune to romanticizing. Many boys dream of being President, King, or Premier. Others dream of discovering lost cities in the Amazon.
