Many of us are no strangers to the experience of a traumatic event. For some, however, such experiences can lead to long-term mental health conditions, including post-traumatic stress disorder (PTSD). Although PTSD was first formally identified in combat war veterans, later research revealed that it also occurs in non-military populations following other life-threatening or deeply distressing events.
Individuals with PTSD often experience persistent levels of anxiety and fear that can significantly impact their mental health and overall quality of life, affecting everything from their ability to work to their family and home life. Existing treatments for PTSD frequently involve revisiting traumatic memories or engaging in immersive therapeutic experiences, which may feel unappealing or be inaccessible for some individuals. But what if a potential treatment option could draw from something universally accessible—a dream? More specifically, a lucid dream.
In our latest study on lucid dreaming, titled Lucid Dreaming and Sleep Characteristics in PTSD, we explored the relationship between sleep metrics and lucid dreaming in adults with chronic PTSD symptoms.
Treating PTSD with Lucid Dream Therapy
In a lucid dream, an individual is aware they are dreaming and may also be able to influence or control the dream’s content. Lucid dreaming is when you realize you are dreaming while the dream is still happening. It feels like waking up inside the dream instead of waking up in bed. The world around you is still a dream, but you know it is not real. Because of that awareness, you can often influence what happens. People describe choosing where to go, what to do, or even changing the environment, like flying or restarting a scene. The level of control varies and can fade if you get too excited or lose focus.
This type of dreaming most commonly occurs during rapid eye movement (REM) sleep, though lucid dreams have also been reported during non-REM sleep stages. There are established techniques, like the one we used here, that increase the likelihood of lucid dreams.
Lucid dreaming during nightmares is relatively common among veterans with PTSD, highlighting its potential therapeutic accessibility. Through lucid dream therapy, individuals with PTSD can learn to recognize and influence their dreams, allowing them to confront and reshape traumatic experiences within a controlled and safe environment. For example, in prior research, we observed reduced PTSD symptoms among 50 participants following lucid dream training.
In this present study, we examined sleep metrics from overnight recordings of individuals with PTSD to determine whether specific sleep characteristics were associated with the occurrence of lucid dreaming. While the ability to experience lucid dreams varies widely from person to person, sleep-related factors and individual characteristics, such as mindfulness practices and certain cognitive abilities, may help explain these differences and offer insight into how lucid dreaming can be intentionally supported.
Dream Monitoring in Individuals with PTSD
Adults who self-reported chronic PTSD symptoms were recruited for this study. Participants also reported experiencing nightmares of moderate frequency and intensity. Over the course of the study, individuals participated in a six-day online lucid dreaming workshop. Following the workshop, participants were instructed to wear a brainwave-recording headband during sleep and to complete morning surveys, including detailed dream reports and a 12-item lucidity questionnaire, based on the previous night’s dreams. Measures of well-being and symptom severity were also collected before and after the workshop.
The Results
A total of 168 nights of EEG data were collected from 27 participants, with lucid dreams being reported on 25 of those nights. After comprehensive and robust statistical analysis, several sleep metrics were found to be associated with the likelihood of experiencing lucid dreams. We also recorded their brainwaves throughout the night with a portable EEG headset. This project is a collaboration between IONS and Interaxon, the most widely used EEG wearable company. They collaborate with relatively few researchers, so we feel fortunate.
Of the sleep metrics, sleep onset latency, which is the amount of time it takes to fall asleep, emerged as the strongest and most consistent predictor of lucid dreaming. Increased wake after sleep onset (WASO), a measure of sleep fragmentation, was also associated with a higher likelihood of lucid dreaming among participants with PTSD symptoms. This finding suggests that structured or intentional disruptions to sleep may help support lucid dreaming without necessarily compromising overall sleep quality.
The delta EEG activity of the brain was another sleep metric that stood out during the study. Recent research further indicates that lucid dreaming is associated with distinct patterns of brain activity during REM sleep, particularly within slower delta brainwaves. The differences in delta activity can help distinguish lucid dreams from typical REM dreams. However, the results of this present study indicate that lower levels of delta activity may represent more than a signature of REM sleep, instead reflecting a brain state associated with heightened alertness, self-awareness, and awareness of the dream state.
Translating Dreams into Clinical Insights
Overall, these findings point to a meaningful relationship between sleep quality, brainwave activity, and the capacity for lucid dreaming. Patterns in sleep continuity and brain activity appear to influence when lucid awareness arises, offering measurable ways to study a process that has often felt elusive. These insights are especially relevant for individuals with PTSD who often suffer from sleep disruption and recurring nightmares. By better understanding the conditions that support lucid dreaming, future interventions may be able to use sleep itself as a tool for reducing distress and strengthening emotional regulation in individuals with PTSD. Furthermore, this work adds to growing evidence that lucid dreaming reflects an active, self-aware state of consciousness with potential benefits that extend beyond clinical treatment.
