  1. LUCID DREAMING Ngan Diep Kim Fleck Stephen Johnson David Yoshida

  2. Outline • Discussion Questions • Introduction • History • Characteristics of Lucid Dreaming • Physiological Aspects • Usefulness of Lucidity • Methods of Induction • Conclusion

  3. Discussion Questions • Could there be consciousness during sleep? • Do we have deliberate control over our actions in dreams? • What is the nature of imaginary worlds? • Is lucid dreaming an altered state of consciousness?

  4. Introduction • What is lucid dreaming? • Dreams in which you know that you are dreaming. • Levels of lucid dreaming and awareness • High-level lucidity • Low-level lucidity • How common are lucid dreams? • "About 58% of the population have experienced a lucid dream at least once in their lifetime, while about 21% report it with some frequency (one or more a month). – Jayne Gackenbach

  5. History • 415 AD written in a letter by St. Augustine. • Practiced by Tibetan Buddhists for a thousand years through a form of dream yoga • 1913 Term coined by Frederick Van Eeden • Modern research- Stephen LaBerge and Lynn Nagel of Stanford University

  6. CHARACTERISITICS • The beginning of lucidity is marked by distinct eye movements • Occurs late during the REM sleep cycle • Induced by some sort of “cue” • Recognition of this “cue” is made possible by higher cortical arousal • Waking up from a lucid dream feels more real than waking from a normal dream • This is due to the higher cortical arousal experienced during lucid dreaming

  7. PHYSIOLOGICAL ASPECTS • Is there a correspondence between actions of the dreamer and muscle activity and electrical responses? • Dream Actions • (Schatzman, Worsley, and Fenwick 1988) • Dream Sex • (LaBerge, Greenleaf, and Kedzierski 1983)

  8. Usefulness of Lucidity • Adventure and Excitement • Practice/Rehearsal • Creative Problem Solving • Therapeutic • What is the nature of the dream world?

  9. Methods of Induction • Mnemonic Induction of Lucid Dreaming (MILD) • Mindfulness • External Signals • Electric Shock to the wrist • Dream Light (LaBerge 1985) • How long do dreams last?

  10. Conclusion • Is lucid dreaming an ASC? YES • How long do dreams take? About 13 sec • Is there a correspondence between actions of the dreamer and muscle activity and electrical responses? YES • What is the nature of the dream world? We don’t know.
