A lucid dream is a type of dream in which the dreamer becomes aware that they are dreaming. This awareness can allow them to have some degree of control over the dream's content, such as the ability to manipulate the dream environment, interact with dream characters, or even fly.
Lucid dreaming can happen spontaneously or can be cultivated through various techniques, such as reality checking, keeping a dream journal, and practicing mindfulness. Some people use lucid dreaming for purposes like problem-solving, creative exploration, or simply for entertainment and adventure within the dream state.
The phenomenon occurs during the REM (rapid eye movement) stage of sleep, when most vivid dreaming takes place. While many people experience lucid dreaming at some point in their lives, some individuals actively practice it to enhance their dream experiences.
