New research published in the journal Communications Psychology has explored why people dream about certain things. The study found that dream content is often shaped by a person’s personality and shared life experiences.
Researchers collected data from nearly 300 adults over two weeks. Participants recorded their daily experiences and their dreams. The study also looked at sleep patterns, personality traits, and cognitive abilities. This process resulted in more than 3,700 reports.
The team used advanced natural language processing, or NLP, techniques to identify patterns and semantic structures in the dreams. They found that individual traits and shared life experiences influence what people dream about.
For example, data gathered during the height of the pandemic showed that dreams were heavily influenced by world events at that time. People reported emotionally intense dreams and dreams about limitations. As the pandemic went on, those dreams began to subside. This suggests that as people adapt to new situations, their dreams also change.
The study also looked at how personality affects dreams. Participants who were more prone to mind-wandering reported fragmented, bizarre, and rapidly changing dreams. Vivid and immersive dreams were more common for participants who believed that dreams have meaning and significance.
The NLP data showed that everyday life is transformed, almost warped, by dreams. Participants described their waking lives and their dreams. The language processing techniques showed that dreams often reorganize or reinterpret waking events.
Study authors wrote that rather than being a direct replay of daily experiences, dreams may offer a hyper-associative reinterpretation of past events and future expectations. Dreams can weave together distant elements into coherent, though often bizarre, scenarios.
Lead study author Valentina Elce, Ph.D., said the findings show that dreams are not just a reflection of past experiences. They are a dynamic process shaped by who people are and what they live through. She added that by combining large-scale data with computational methods, researchers were able to uncover patterns in dream content that were previously hard to detect.
The study authors noted that more research is needed to understand the mechanisms behind dream content. However, using NLP for dream research could be a new and effective way to learn more about dreams, consciousness, and memory.
The study concluded that dreaming serves as a mechanism through which the brain processes and integrates newly acquired memories. Over time, the brain gradually strips away or reduces the emotional intensity of those memories.
The research suggests that dreams are shaped not only by individual lived experiences but also by shared experiences, emotions, and personality traits. While the full meaning and mechanisms of dreams may remain a mystery, this study provides a clearer picture of the factors that influence what people dream about at night.
