Lucid dreaming is when one is aware that they are dreaming while dreaming. Some key points about lucid dreaming are: - A lucid dream can start as a normal dream that later becomes lucid, or one can go directly from wakefulness into a lucid dream state with no break in consciousness. - During a lucid dream, the dreamer has a greater ability to exert some control over their participation in the dream or manipulate their imaginary experiences. - Techniques like mantra repetition and waking up between sleep cycles can help induce lucid dreams according to research.
