Lucid dreaming—being aware that one is dreaming while still asleep—is rare but can be trained by regularly questioning whether current experience is real or a dream. Virtual reality (VR) scenarios containing dream-like elements enhanced this training. Over four weeks, volunteers who received VR-assisted lucid dreaming training showed significantly greater increases in lucid dreaming than those who received no training. Eye-signal-verified lucid dreams during polysomnography supported these behavioral results. Potential mechanisms include synthetic dream-like experiences, incorporation of VR content into dream imagery as memory cues, and dissociative effects of VR that may amplify lucid dreaming training during wakefulness.
Nightmares are less frequent and less distressing for people who practice mindful acceptance—the ability to experience thoughts and feelings without judgment—rather than merely mindful presence, or paying attention to the present moment. Two studies, one with 338 participants and another with 187 frequent lucid dreamers who used meditation and lucid dream induction techniques, found that acceptance was more strongly linked to fewer nightmares and less nightmare distress than presence. People with high meditation expertise and practice of lucid dreaming techniques reported the lowest nightmare frequency. Among frequent lucid dreamers, more lucid dreaming was associated with higher mindfulness. The findings suggest that the two facets of mindfulness play distinct roles in dream quality, with potential clinical applications.
