What is Lucid Dreaming?
A lucid dream is any dream in which one is aware that one is dreaming.
How Lucid Dreaming works.
A lucid dream can begin in one of many ways. A dream-initiated lucid dream (D.I.L.D.) starts as just a normal dream, and the dreamer eventually concludes it is a dream. A wake-initiated lucid dream (W.I.L.D) occurs when the dreamer goes from a normal waking state directly into a dream state, with no apparent lapse in consciousness. The wake-initiated lucid dream occurs when the sleeper enters REM sleep with unbroken self-awareness directly from the waking state
