A May 2025 study in Communications Psychology sheds light on dream recall, revealing factors such as sleep patterns, daytime mind wandering, and personal traits that boost dream remembering. The findings offer timely insights for Thai readers navigating busy urban life and evolving sleep routines.
In Thailand, dreams are often viewed through a cultural lens as omens or messages. Science treats dreams as a window into brain activity during sleep. The study helps explain why some people recall more details than others and what that reveals about memory, consciousness, and mental health.
The study followed 217 healthy adults aged 19–70, who kept dream diaries for 15 mornings while researchers monitored sleep stages and conducted cognitive tests. Longer periods of lighter sleep with more REM sleep were linked to richer dream recall. Younger participants tended to remember more details, while recall dipped in winter compared with spring, suggesting environmental or circadian influences. Senior author Dr. Giulio Bernardi noted that most dreams fade quickly from memory, but understanding these differences advances consciousness research.
For Thailand, where seasonal shifts are subtler yet light exposure shifts with the monsoon, the study invites localized exploration. Since lighter sleep boosted recall, Thai lifestyles—such as late-night socializing in cities or early farming schedules in rural areas—could shape sleep patterns and dream recall. This is especially relevant to discussions about urban-rural health disparities in the country.
A notable finding was the link between daytime mind wandering and dream recall. People who report more daytime daydreaming also remember more dreams, suggesting the brain’s tendency to generate spontaneous mental experiences affects waking and sleeping cognition. Lead author Dr. Valentina Elce emphasized that daily mental activity and dreaming are interconnected.
Practically, the research showed that keeping a dream journal helped participants improve recall over time. Recording dreams can train the brain to retain nocturnal narratives, offering a simple, accessible method for curious readers to explore inner experiences. This resonates with Thailand’s younger generation, where journaling and online sharing of dreams are popular for self-reflection and stress management.
Experts outside the study praised its longitudinal design and multifaceted approach to sleep and cognition. Some cautioned that the sample was Italian, raising questions about cultural scope. In Thailand, where spiritual beliefs about dreaming are deeply rooted, cultural context may influence how openly people discuss dream content.
Dream formation remains a topic of scientific debate. Researchers suggest dreams may help consolidate memories and process emotions, though consensus is evolving. The field explores possibilities from memory integration to emotional processing. Stress, trauma, and mental health conditions can shape dream content, including nightmares, which cognitive-behavioral therapies can help alleviate.
Thai sleep clinicians and mental health professionals can apply these insights to daily care. For individuals facing high study, work, or social stress, evidence-based therapies such as cognitive behavioral therapy for insomnia can improve sleep quality and reduce nightmares. This approach is increasingly available in urban clinics and university counseling centers as part of broader wellness programs.
Most people do not need alarm over dream recall. Experts note that most people remember few or no dreams on any given night, even though dreaming occurs for roughly two hours nightly. Dream recall varies naturally and becomes a concern only if it disrupts sleep or causes distress.
Looking ahead, researchers plan to analyze dream content more closely to see whether dreaming patterns signal neurological changes, including dementia. If successful, dream analysis could become a non-invasive biomarker for cognitive health, opening new avenues for Thai healthcare in an aging society.
Dreams have long influenced Thai literature, art, and folklore, appearing in temple murals, stories, and family discussions. The meeting of neuroscience and tradition invites thoughtful dialogue that strengthens public understanding of sleep science while honoring cultural heritage.
Practical steps for readers include keeping a dream journal, evaluating sleep routines, and seeking professional help for persistent sleep difficulties or distressing dreams. Schools and community groups could incorporate sleep education into wellness activities to reduce stigma around sleep disorders and mental health challenges.
To stay informed on ongoing research, follow reputable medical sources and national health authorities. Open conversations about dreams—whether as fascinating stories or reflections of brain health—can enrich personal insight and community wellbeing.
