Abstract
I investigated individual differences in the frequency of lucid dreams experienced by university students and related factors. In Study 1, approximately 700 university students were surveyed regarding lucid dreams, nightmares, the frequency of sensory experiences in dreams, vividness and control of imagery, fantasy proneness, and nightmare distress. Results indicated that the frequency of lucid dreaming was not significantly related to imaginative ability, while covariance structure analysis indicated that the frequency of lucid dreaming was influenced by two systems: the frequency of nightmares and the frequency of dream recall. In Study 2, approximately 7,900 university students were surveyed. Four groups with the 5% highest or lowest frequency of lucid dreams and nightmares were examined for intergroup differences in the mean frequency of sensory and emotional experiences in dreams. Results suggested that among the group with a high frequency of lucid dreams, there may be a group with nightmare-related experiences that frequently experiences distressing negative dreams and a group with few nightmares and a high proportion of positive emotions that are unrelated to nightmares. Moreover, results indicated that those who frequently experienced nightmares and lucid dreams may experience slightly less vivid colors in their dreams than those who did not experience lucid dreams.
