Dream - reality confusion (DRC) is a difficulty or an impossibility to determine whether an event or an experience took place during wakefulness or if it was the content of a dream. The main goal of the present study was to explore characteristics of participants from the general population who often/very often experience DRC in comparison with those who never/almost never experience it. Altogether, 82 participants were investigated with a set of questionnaires. Results of the study indicate that individuals prone to DRC - in comparison with those who rarely or do not at all experience DRC - more often experience various sleep-related phenomena, and they also have higher neuroticism, thinner boundaries, higher dream recall frequency, and more involved attitudes toward dreams. Furthermore, some trends were revealed, suggesting that high level of borderline personality disorder features, fantasy proneness, and dissociative symptoms may be related to higher probability of experiencing DRC. The limitations of the study and future research directions were also discussed.
