Spontaneous lucidity is quite rare but can be increased through cognitive training techniques (Schadow et al., 2018) or, as seen in previous studies, video game play has also been suggested to increase lucidity in dreams (Gackenbach, 2006). Therefore, the present study explores the effects that exposure to virtual reality environments have on self-reported lucidity scores, as measure by the Dream Lucidity Questionnaire. In total, 39 participants were equally randomized and distributed by three groups, that ranged from full training to no training whatsoever: Virtual Reality, Active Control and, Passive Control. It was found that participants in the Virtual Reality condition had significantly increased their scores in comparison with the Passive Control Condition (p=0.003). This study comes to strengthen the hypothesis that VR tech might be a useful tool in lucid dream research or simply to whomever wishes to develop this “skill”.engLucidityVR techCognitive trainingmaster thesis202834506
