Sleep, Dreaming, and Virtual Reality for Mental Health
What this study is about
People spend approximately one-third of their lives asleep, yet sleep is often underused as an opportunity to support psychological well-being. Contemplative traditions, including Tibetan Dream Yoga, have developed practices that use waking imagination and lucid dreaming to explore perception, awareness, and habitual patterns of thinking.
View original scientific description
People spend approximately one-third of their lives asleep, yet sleep is often underused as an opportunity to support psychological well-being. Contemplative traditions, including Tibetan Dream Yoga, have developed practices that use waking imagination and lucid dreaming to explore perception, awareness, and habitual patterns of thinking. Recent advances in sleep monitoring, dream communication, and lucid dream induction now make it possible to study these practices using scientific methods. This study is a randomized controlled trial designed to examine the feasibility and effects of a Dream-Yoga-inspired intervention compared with an active control condition. The intervention combines waking and dreaming practices that are adapted for individuals without prior experience and delivered using virtual reality-based training and home sleep technology. The program is designed to be scalable and culturally neutral, without requiring prior knowledge of contemplative or religious traditions. The primary goals of the study are to characterize sleep and waking neurophysiology associated with Dream-Yoga-inspired practices and to evaluate whether participation is associated with changes in sleep-related brain activity and cognitive processes. Outcomes include measures of lucid dreaming, sleep physiology, and waking cognitive and perceptual processes. Anxiety will be assessed as an exploratory outcome to examine whether participation may be associated with changes in emotional experience. This study is not designed to provide treatment for anxiety or other clinical conditions. Results from this study will help inform the development of scalable sleep-based mental training approaches and guide future research on the use of dreaming and sleep practices to support psychological health and well-being.
Interventions
BEHAVIORAL
Dream Yoga Inspired Intervention
This customized contemplative training will guide participants in exploring techniques used in Tibetan Dream Yoga. Strategies in Tibetan manuals are thus transferred to a modern context and adapted as a group intervention. Goals will be set for dreaming that include gaining lucidity, a degree of volitional influence over the dream. Participants will be instructed on how to work with their dream-world self-concept, which can include changing the environment deliberately, making other individuals appear, and switching identities with other individuals in the dream. Wearable devices will be used to present cues during sleep both to provoke lucidity and to remind individuals of Dream-Yoga exercises to be engaged during sleep. The intervention includes both wake- and sleep-based instructions, with instructions on learning to apply the new orientation in their daily lives.
BEHAVIORAL
Sleep Health Enhancement Program (SHEP)
The control group will receive a modified version of the Health Enhancement Program (HEP), which was developed as an active control condition for mindfulness-based interventions, with a particular focus on sleep hygiene and dream journaling. It controls for several non-specific factors such as expectations of positive change, group support, behavioural activation, facilitator attention, at-home practice, treatment duration, and format (MacCoon et al., 2012; Rosenkranz et al., 2013). Our modified HEP will be structurally equivalent to the Dream-Yoga condition, with high similarity on non-program-specific factors, including timing and number of sessions. The two VR sessions will focus on relaxation. Participants will be taught positive health-enhancing practices, such as healthy diet and gentle exercise, with activity-based sessions covering exercise, sleep, dreaming, stress, anxiety, nutrition, journaling, music enjoyment, and drawing.
Primary outcome measures
Changes in frontal midline theta
Time frame: Baseline to 8 weeks
The intervention will preferentially increase frontal midline theta during a short period of breath meditation (one recording session before and one after the intervention); EEG power band-passed at 4-10 Hz will be quantified and related to findings on self-referential processing (Nondual Awareness Dimensional Assessment)
Changes in Sleep Architecture
Time frame: Baseline and 8 weeks
Sleep architecture will be compared with regard to time spent in each sleep stage, microarousals, slow-wave power, sleep spindles, and coupling between slow waves and spindles. Spectral power differences in different sleep stages.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.

Exclusion criteria
- We will exclude people who self-report any of the following:
- history of an established meditative practice
- psychological or psychiatric disorders (other than mild anxiety)
- sleep disorders, nightshift work in the past month, extreme chronotype or irregular sleeping pattern
- use of recreational drugs in the past month
- history of asthma, seizures or heart problems

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
