Dream habits in a large cohort of preteens and their relation to sleep and nocturnal awakenings

SummaryThe present study examined dream habits, and their relation to sleep patterns, in 1151 preteens (597 boys; 554 girls; 11.31 ± 0.62 years old). Dream questionnaires assessed the frequency of dream recall, nightmare, and lucid dream, as well as the intensity of emotions experienced in dreams. Sleep variables included sleep duration and efficiency, but also different measurements of nocturnal awakenings. Among the preteens, 49.21% of them reported that they recalled dreams several times a week or almost every morning over the past few months. In addition, 52.00% of the preteens reported that they experienced nightmares, and 45.48% lucid dreams, less than once a month or never over the past few months. No gender differences were observed in dream variables. Nocturnal awakenings were linked to all dream variables, while sleep duration and sleep efficiency were related to nightmare frequency and emotions in dreams. Importantly, sleep duration and sleep efficiency were not associated with dream recall nor lucid dream frequency, with Bayesian analyses supporting the null hypothesis. These findings offer a comprehensive understanding of preteens’ dreams and their connection to key sleep aspects.
