New Research Unpacks Why and How We Dream About Certain Things
Dreams remain one of life’s biggest puzzles. They can be frightening, pleasant, clear, and strange. According to a study published in the journal Communications Psychology, the content of dreams 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 resulted in more than 3,700 reports.
The team used advanced natural language processing to find patterns in dream content. 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 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 fade as the pandemic went on. This suggests that as people adapt, their dreams also adapt.
The study also found links between personality and dream content. 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 dreams have meaning and significance.
The natural language processing data also showed that everyday life is transformed by dreams. Participants described their waking lives and their dreams. The analysis 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 wrote.
The researchers noted that more work is needed to understand the mechanisms behind dream content, such as how personality influences dreams. Still, the findings bring science 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.”
Using natural language processing for dream research could be a new and effective way to learn more about dreams, consciousness, and memory.
The study authors wrote that dreaming serves as a mechanism through which the brain processes and integrates newly acquired memories. It gradually strips away or reduces their emotional intensity.
People may never fully understand dreams, their meaning, or the mechanisms behind them. But this research shows that dreams are shaped by lived experiences, shared experiences, emotions, and personalities.
