New Research Unpacks Why We Dream About Certain Things
Dreams are one of life’s greatest mysteries. They can be scary, enjoyable, vivid, and strange. But according to new research published in the journal Communications Psychology, the content of our dreams is often determined by our 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 resulted in over 3,700 reports.
The team used advanced natural language processing techniques to identify patterns and semantic structures in dreams. They found that individual traits and shared life experiences influence dream content.
For example, data gathered during the height of the pandemic showed that dreams were heavily influenced by the state of the world at that time. People reported emotionally intense dreams and dreams about limitations. Those dreams began to subside as the pandemic went on, suggesting that as people adapt, their dreams adapt as well.
In terms of personality, the study found two key things. Participants who were more prone to mind-wandering reported fragmented, bizarre, and rapidly changing dreams. Vivid, immersive dreams were more common for participants who believed that dreams have significance and meaning.
The language processing data also revealed that everyday lives are transformed, almost warped, by dreams. Participants described their waking lives and their dreams. The techniques showed that dreams often reorganize or reinterpret waking events.
“Rather than constituting a direct replay of daily experiences, dreams may offer a hyper-associative reinterpretation of past events and future expectations, weaving together apparently distant elements into coherent, though often bizarre, scenarios,” the study authors explained.
The study authors noted that more research is needed to understand the mechanisms underlying dream content, such as how personality actually influences dreams. But the findings bring us closer to understanding the mystery.
“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 lead study author Valentina Elce, Ph.D. “By combining large-scale data with computational methods, we were able to uncover patterns in dream content that were previously difficult to detect,” she added.
Using natural language processing for dream research could be a new and effective way to continue learning about dreams, consciousness, and memory. The study authors wrote, “Dreaming serves as a mechanism through which the brain processes and integrates newly acquired memories, gradually stripping away or reducing their emotional intensity.”
We may never fully understand dreams, their meaning, or the mechanisms behind them. But this research shows one thing for certain: dreams are shaped not only by lived experiences, but also by shared experiences, emotions, and personalities.
