For years, the notion that dreams are random neural noise has persisted. But a new study from the IMT School for Advanced Studies Lucca in Italy suggests otherwise. Published in Communications Psychology, the research draws on more than 3,700 dream reports collected from 287 participants aged 18 to 70 over a two-week period. The findings indicate that dream content is shaped by a combination of personality traits and real-world experiences.
What Shapes Our Dreams?
The study used advanced natural language processing (NLP), a form of artificial intelligence, to analyze how participants described their daily lives and dreams. Researchers also gathered data on sleep quality, cognitive patterns, and psychological characteristics. The results show clear patterns: people who tend to jump between unrelated thoughts during the day often report dreams that feel scattered and change rapidly. Conversely, those who see dreams as meaningful experience them as more vivid and immersive.
External events also play a significant role. During the COVID-19 pandemic, dreams became more intense and frequently focused on themes of restriction and confinement. These patterns faded as life returned to normal, suggesting that dreams shift alongside our psychological state. This aligns with broader research on how stress and trauma affect sleep, as seen in studies on urban vs rural upbringing and mental health.
Rather than replaying daily life, dreams transform it. Routine elements such as workplaces, hospitals, or schools rarely appear as direct copies. Instead, they are reorganized into unfamiliar and often surreal scenarios, blending different contexts and perspectives. “Our findings show that dreams are not just a reflection of past experiences, but a dynamic process shaped by who we are and what we live through,” said Valentina Elce, lead author of the study.
The study also highlights how AI can advance dream research. NLP models can analyze dream reports with accuracy similar to human reviewers, opening new opportunities to study consciousness, memory, and mental health at scale. This methodological advance could be compared to other AI applications, such as how ChatGPT mimics abusive language in heated arguments.
While the French folk belief that eating cheese before bed leads to wild dreams remains unproven, the research suggests that measurable forces—both internal and external—shape our nightly adventures. The study's European roots, conducted at a leading Italian institution, underscore the continent's role in advancing cognitive science.
