Dream lucidity, the awareness of consciousness in dreams, is linked to functions that support reality monitoring in differentiating between internally and externally generated memories. However, lucid dreams have been argued to result from thin reality–fantasy boundaries that lead to reality monitoring errors. To examine the relationship between dream lucidity and reality monitoring, we recruited 31 college students to rate their dream lucidity for 7 days and then complete a reality monitoring test in Experiment 1, observing a positive correlation between dream lucidity and reality monitoring. In Experiment 2, 109 participants rated dream lucidity and the memory characteristics of perceived and imagined events. Dream lucidity was negatively correlated with differences in sensory details between the memories of perceived and imagined events. The findings indicate that individuals with high dream lucidity have a superior ability to discriminate between externally and internally generated events that are susceptible to reality monitoring errors.
