A lucid dream is usually defined as a dream in which one is aware that one is dreaming. Once a person becomes aware that he or she is dreaming, he or she can do anything imaginable. Uses of lucid dreaming include confronting fears, problem-solving, and having fun. Some people have lucid dreams without any effort, particularly during childhood. For most adults and adolescents, however, some active participation is required in order to experience lucid dreams with any regularity.
In the early ages of history, lucid dreams were usually dealt with a lot of mysticism, and were usually associated with divine revelations. Actually, Indian shamans would be recognised by them having a lucid dream, as it was associated with the spiritual world. Further on, Tibetan Buddhists were practising a form of yoga responsible for making a person stay conscious while dreaming. The first person to use the term "lucid dreaming" was the psychiatrist Frederik van Eeden, describing them as when someone would have the insight of being dreaming.

Lucid dreams in popular cultureEdit
There are few movies, television shows, and documentaries that involve lucid dreaming. A few movies that have lucid dream-like content are: The Matrix, Inception, Mirror Mask, What dream may come, and Waking Life. Out of those movies, only Waking Life uses the words lucid dreaming (although reality checks are featured in Inception). The only documentary on lucid dreaming is called Explorers of the Lucid Dream World [http://luciddreamexplorers.com]. Despite that lucid dreaming is a profound state of consciousness, and is a metaphor for enlightenment, it does not hold much of a presence in popular culture.
