2.1 WHY HAVE LUCID DREAMS?
Upon hearing about lucid dreaming for the first time, people often ask, "Why should I want to have lucid dreams? What are they good for?" If you consider that once you know you are dreaming, you are restricted only by your ability to imagine and conceive, not by laws of physics or society, then the answer to what lucid dreaming is good for is either extremely simple (anything!) or extraordinarily complex (everything!). It is easier to provide a sample of what some people have done with lucid dreaming than to give a definitive answer of its potential uses.
What is Lucid Dreaming?
The basic definition of lucid dreaming requires nothing more than becoming aware that you are dreaming. However, the quality of lucidity can vary greatly. When lucidity is at a high level, you are aware that everything experienced in the dream is occurring in your mind, that there is no real danger, and that you are asleep in bed and will awaken shortly. With low-level lucidity, you may be aware to a certain extent that you are dreaming, perhaps enough to fly or alter what you are doing, but not enough to realize that the people are dream representations, or that you can suffer no physical damage, or that you are actually in bed.
