What is lucid dreaming?

Lucid dreaming is a state of sleep where you are aware that you are dreaming and can consciously influence the actions and contents of the dream. Typically occurring during REM sleep, lucid dreaming is experienced by about 20% of people, with a small percentage having it almost every night. Some people find that regular lucid dreaming can make their sleep feel less restorative. The phenomenon often leads individuals to feel a strong attachment to their dreams, sometimes feeling a compelling need to discuss these dreams with others 1.
