A lucid dream is a dream in which the person is aware that he or she is dreaming while the dream is in progress, also known as a conscious dream. When the dreamer is lucid, he or she can actively participate in the dream environment without any of the limitations that otherwise would feel natural to persons who incorrectly believe they are in the "real" waking world. Lucid dreams can be extremely real and vivid depending on a person's level of self-awareness during the lucid dream.

One problem faced by people wishing to lucid dream is awakening prematurely. This premature awakening can be frustrating after investing considerable time into achieving lucidity in the first place.

Stephen LaBerge proposed two ways to prolong a lucid dream. The first technique involves spinning one's dream body. He proposed that when spinning, the dreamer is engaging parts of the brain that may also be involved in REM activity, helping to prolong REM sleep. The second technique is rubbing one's hands. This technique is intended to engage the dreamer's brain in producing the sensation of rubbing hands, preventing the sensation of lying in bed from creeping into awareness. LaBerge tested his hypothesis by asking 34 volunteers to either spin, rub their hands, or do nothing. Results showed 90% of dreams were prolonged by hand rubbing and 96% prolonged by spinning. Only 33% of lucid dreams were prolonged with taking no action.[45]

Once the initial barrier of lucidity is broken, the dreamer’s next obstacle is the excitement of being conscious within a dream. It is key that the dreamer immediately relaxes upon becoming lucid. There are many methods that work, but in general saturating any of the senses with stimuli from the dream is important. Vision is usually the first sense to fade away, with touch commonly being the last. If the dream starts to fade, you can grab a hold of anything close by, making sure to feel the tactile sensation. Other techniques include shouting in a loud and clear voice, “INCREASE LUCIDITY!” inside the dream. People are often reluctant to do this, but it significantly stabilizes the dream and increases its vividness. The well-known author, Carlos Castaneda, suggests that the dreamer touch their tongue to the roof of their mouth, an action that greatly increases the realness of the dream.
