QuickWrite: Illusions

Illusions are a beautiful thing in life. Believing in illusions is a natural coping mechanism for humans to deal with the hardships that life will inevitably throw at you. This reminds me of lucid dreamers. There are people who spend most of their life controlling their dreams. They dream so vividly, that sometimes they confuse their real life with their dreams. Although the feelings they have during dreams is an illusion, it feels completely real to them. If we believe that it something is real, and we enjoy the illusion or dream being set up in front of us, then what is the harm? Is it even worth living a real life if your dream life leaves you so much more fulfilled? Other than the fact of living a life of dreams is a very selfish life, the detachment from the real world is no issue to the rest of the world, because if the person is enough of a fool to believe the illusion, then he or she probably would not offer much to the world anyways.
