The purpose of this study was to verify the Jungian concept of synchronicity and to utilize lucid dreaming techniques for the selected dreamers to experience synchronistic dreams more frequently.

1248 dreams were collected from 416 Korean college students, Yongin, South Korea: 198 males (M age = 20.46 years, SD = 1.32) and 218 females (M age = 20.17, SD = 1.26). The collected dreams were coded by the Sang Bok Lee Neurosynchronistic Dream Scales. 36 dreams (2.88%) were evaluated as synchronistic and 10 dreamers were selected randomly and voluntarily: six females (M age = 20.19, SD = 1.24) and 4 males (M age = 20.47, SD = 1.35). Total twelve sessions for lucid dreaming technique training (one-hour session, twice per week, and six-week duration) were conducted and the trained dreamers reported their dreams during and after the twelve sessions.

50 dreams that were collected during and after the lucid dreaming sessions were coded and found as significantly increased in terms of synchronistic dream frequency mode (9 dreams, 18%, when compared with the untrained dreamers: p < 0.0001). The results were empirically supported by “Lee Acculturation Dream Scale” (Lee, Sang Bok, 2005: Psychological Reports, 96, 454–456), “The Sang Bok Lee Neurocognitive Dream Orientations Scales” (2010, European Psychiatry), and by “Dreaming Brain and Acculturative Mind” (Lee, Sang Bok, 2010, European Psychiatry).

Lucid dreaming constitutes a future-oriented intentionality, adaptive function of brain/mind, neural plasticity, and a certain realization of the Jungian concept of synchronicity with measurable differences from untrained dreamers.
