A study from the IMT School for Advanced Studies Lucca suggests that dreams aren’t just random mental noise.
Instead, how vivid, emotional or confusing a dream feels may depend on a mix of personality traits and real-life experiences.
Published in Communications Psychology, the research analyzed more than 3,700 reports of both dreams and waking life experiences from 287 adults 18 to 70.
Participants tracked their experiences over a two-week period, while researchers also collected data on sleep patterns, personality traits, cognitive ability and psychological profiles.
How AI Was Used to Study Dreams
To make sense of the huge amount of text data, researchers used natural language processing, a type of AI that can analyze meaning in written descriptions.
This allowed them to look at dream reports in a structured way instead of treating them as isolated stories.
What they found was that dreams aren’t chaotic at all — they actually show consistent patterns linked to personality and life context.
Rather than replaying daily life like a recording, the brain reshapes it during sleep.
Everyday environments like schools, hospitals or workplaces don’t show up exactly as they are.
Instead, they get blended, distorted and rebuilt into more emotional and sometimes surreal scenes.
This suggests dreams are more of a reconstruction process than a replay, where memories, imagination and expectations all get mixed together.
How Personality Shapes Dream Patterns
One of the clearest findings was that personality plays a big role in dream style.
People who tend to “mind-wander” a lot during the day were more likely to report dreams that felt fragmented, shifting quickly between scenes or ideas.
On the other hand, people who believe dreams are meaningful or important often described them as more vivid, immersive and emotionally rich.
So even though everyone dreams, the style of dreaming seems to vary quite a bit from person to person.
How Real-World Events Show Up in Dreams
The study also looked at how major events affect dream content.
During the COVID-19 lockdown period, researchers saw a noticeable shift in dream themes.
People reported more emotionally intense dreams, often involving restriction, isolation or being unable to move freely.
As life gradually returned to normal, these themes started to fade, suggesting that dreams adapt alongside psychological responses to real-world stress and change.
AI Is Changing Dream Research
The study also shows how useful AI tools can be in psychology research.
The natural language processing systems used in the study were able to interpret dream descriptions with accuracy close to human judgment, making it possible to analyze large-scale dream data more consistently than before.
Researchers say this could open the door to better understanding of memory, consciousness, sleep and even mental health patterns in the future.
