Although dreams may reflect one\u2019s mental state, few studies have focused on adolescents. Therefore, this study investigated the relationship between dream content and mental health, specifically anxiety disorder and depressive symptoms, among Japanese adolescents. This cross-sectional study obtained data on gender, grade, age, lifestyle habits, weekday sleep duration, anxiety disorder symptoms, depressive symptoms, and dreams from Japanese high school students. The data were analyzed via multiple logistic regression analyses. The prevalence of anxiety and depressive symptoms increased with the frequency of \u201crumination at bedtime\u201d, \u201cmemory of dreams\u201d, \u201cemotional carryover\u201d, and \u201cawakening by frightening\u201d, \u201cunpleasant\u201d, \u201cfilm-like\u201d, \u201cfantastical\u201d, and \u201crecurring\u201d dreams. However, this was not the case for \u201cpleasant dreams\u201d. Furthermore, \u201crumination at bedtime\u201d (anxiety disorder symptoms: adjusted odds ratio: 10.60; 95% confidence interval: 5.92\u201318.97; depressive symptoms: 8.79, 5.58\u201313.87) and \u201cunpleasant dreams\u201d (anxiety disorder symptoms: 5.25, 2.86\u20139.64; depressive symptoms: 10.13, 5.57\u201318.44) exhibited particularly high odds ratios. \u201cRumination at bedtime\u201d and \u201cunpleasant dreams\u201d may serve as early indicators of declining mental health. School- and parent-led interventions aimed at improving mental well-being may help prevent the progression or exacerbation of anxiety and depressive symptoms among adolescents.<\/jats:p>","DOI":"10.3390\/clockssleep7030034","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T05:53:13Z","timestamp":1750917193000},"page":"34","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Association Between Dreams, Anxiety, and Depressive Symptoms Among Japanese Adolescents: A Cross-Sectional Study"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-1587-4103","authenticated-orcid":false,"given":"Yuki","family":"Tanaka","sequence":"first","affiliation":[{"name":"Division of Public Health, Department of Social Medicine, Nihon University School of Medicine, Tokyo 173-8610, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8247-9235","authenticated-orcid":false,"given":"Yuichiro","family":"Otsuka","sequence":"additional","affiliation":[{"name":"Division of Public Health, Department of Social Medicine, Nihon University School of Medicine, Tokyo 173-8610, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-6917-4058","authenticated-orcid":false,"given":"Suguru","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, Nihon University School of Medicine, Tokyo 173-8610, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Itani","sequence":"additional","affiliation":[{"name":"Department of Public Health, International University of Health and Welfare, Narita 286-8686, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomomi","family":"Miyoshi","sequence":"additional","affiliation":[{"name":"Division of Public Health, Department of Social Medicine, Nihon University School of Medicine, Tokyo 173-8610, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1287-7590","authenticated-orcid":false,"given":"Yoshitaka","family":"Kaneita","sequence":"additional","affiliation":[{"name":"Division of Public Health, Department of Social Medicine, Nihon University School of Medicine, Tokyo 173-8610, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,26]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2025, May 12).
