Key Takeaways
New research suggests immersive dreaming can help maintain the feeling of deep, restorative sleep—even when brain activity fluctuates.
Experts say dreams may help the brain process emotions, organize memories, and regulate itself overnight.
Consistent bedtimes, limiting alcohol, and a solid wind-down routine can support REM sleep and increase the likelihood of vivid, restorative dreams.
It goes without saying that dreams are a natural—if mysterious—part of sleep. Whether you expect to or not, your brain resurfaces familiar faces and scenarios—even those we can’t always remember upon waking—during sleep as a way to process and classify memories, relationships, and even our deepest fears. According to a new study conducted by the IMT School for Advanced Studies Lucca, a research institution located in Lucca, Italy, vivid dreams may be the secret to deeper, more restful sleep. But how can you harness dreams for better sleep, and how exactly does it impact your sleep? We dug into the research and tapped a sleep doctor for more information.
How Immersive Dreams Lead to Deeper Sleep
Past research has shown that slow brain waves with minimal activity—or the brain essentially turning off—creates an ideal environment for deep sleep, while dreaming has been linked to Rapid Eye Movement (REM) sleep, which indicates the brain is partially active as we dream. “What stands out in this study is the suggestion that dreaming is structured and functional, not passive and likely part of how the brain resets, organizes, and regulates itself overnight,” says Saema Tahir, MD, quadruple board-certified adult and pediatric sleep disorder specialist.
In the study, researchers analyzed 196 overnight records from 44 healthy adults. Participants spent their nights in a laboratory while their brain activity was monitored during sleep; over the course of four days, these participants were awoken 1,000 times and asked to recall what they were experiencing before waking, along with how deeply they felt they had been sleeping. They reported feeling the deepest sleep after either no conscious experience or after vivid, immersive dreams. “This suggests that dreaming may reshape how brain activity is interpreted by the sleeper: the more immersive the dream, the deeper the sleep feels,” explains Giulio Bernardi, professor of neuroscience at the IMT School for Advanced Studies and senior author of the study. Even when physiological signs showed a decrease in sleep pressure, participants reported that their dreams helped preserve the feeling of deep sleep, acting as a buffer between the outside world and the dreamer’s inner experience.
“If dreams help sustain the feeling of deep sleep, then alterations in dreaming could partly explain why some people feel they sleep poorly even when standard objective sleep indices appear normal,” Bernardi says. “Rather than being merely a by-product of sleep, immersive dreams may help buffer fluctuations in brain activity and sustain the subjective experience of being deeply asleep.”
How to Have More Vivid Dreams—and Achieve Deeper Sleep
“Examples of immersive dreams may be reconnecting with someone meaningful in a peaceful or resolving way, achieving something significant, or traveling somewhere desired,” Dr. Tahir explains. “These dreams often have a strong sensory detail in terms of color and sound, a sense of narrative or purpose, and emotional resolution or curiosity rather than fear. People often wake from these dreams feeling mentally refreshed, lighter, and inspired.”
Although controlling the content of your dreams is largely out of your hands, Dr. Tahir says that protecting and consistently practicing your wind-down routine can lead to meaningful dreams that tend to emerge naturally from a well-protected sleep routine. She suggests prioritizing the following nighttime habits.
Sleeping at the same time: “Protect your REM sleep window by aiming for consistent timing,” Dr. Tahir suggests. “REM is most prominent later in the night, so cutting sleep short reduces REM sleep.” Aim to go to bed at the same time every night for better, more restorative sleep.
Reducing nighttime fragmentation: Dr. Tahir suggests immediately addressing environmental factors like snoring, awakenings, and difficulties initiating or maintaining sleep to prevent the likelihood of poor sleep.
Limiting alcohol intake: Although a glass of wine or two before bed might make you sleepy, Dr. Tahir says excessive alcohol intake can suppress REM sleep.
Creating a consistent wind-down routine: Whether you enjoy journaling, meditation, or taking a hot bath, Dr. Tahir recommends a consistent wind-down routine that can signal to your brain that bedtime is approaching.
Optimizing your sleep environment: Your sleep environment matters beyond aesthetics. “Keeping it cool, dark, and minimizing external disruptions supports deeper, uninterrupted sleep cycles,” Dr. Tahir says.
