Why do some dreams feel so vivid that they seem almost real, while others unfold as confusing fragments that are difficult to remember or understand? New research suggests the answer may depend on a combination of personality, sleep quality, mental habits, and major events unfolding in the outside world.
A study led by researchers at the IMT School for Advanced Studies Lucca found that dreams are not simply random collections of images and thoughts. Instead, they appear to be shaped by both individual differences and shared experiences, including major social disruptions such as the COVID-19 pandemic.
Thousands of Dream Reports Reveal Hidden Patterns
The research, published in Communications Psychology, examined more than 3,700 descriptions of dreams and waking experiences from 287 people between the ages of 18 and 70.
For two weeks, participants recorded their dreams and daily experiences. The researchers also collected information about each person's sleeping habits, personality, cognitive abilities, and psychological characteristics.
