While participants reported lucid dreams on nights the dream mask sent light cues as well as on nights it did not, they were more than twice as likely to have a lucid dream on nights the mask sent cues. Researchers have not yet studied lucid dream masks for potentially negative effects.
However, it is possible the light and sound cues could reduce sleep quality. Similarly, environmental noise exposure triggers a stress response that can disturb sleep and lead to sleep deprivation the following day. Researchers warn that regularly inducing lucid dreams has two potential drawbacks.
It can blur the lines between fantasy and reality, and it may reduce your sleep quality. Lucid dreamers display increased prefrontal cortical brain activity during sleep. In normal sleep, activity in this brain area is inhibited. Further, the WBTB lucid dreaming technique is rooted in disrupting sleep, which may lead to more sleep issues.
Also, while lucid dreams may have some therapeutic potential for people with chronic or PTSD-induced nightmares, other studies suggest otherwise. More research is needed to determine if lucid dreaming or lucid dream masks produce negative effects, whether in terms of sleep quality, mental health, or both.
Lucid dreaming researchers acknowledge that more research needs to be done on how to induce lucid dreaming, with or without a mask. The current body of research is limited, with many studies being either low-quality or having a small number of participants. Beginners may want to start with these techniques before investing in a lucid dream mask. Sarah has covered news topics for digital and print publications.

Ongoing Research on Lucid Dream Masks. What Are Lucid Dream Masks? Then, depending on their specific feature set, lucid dream masks alert the dreamer using audio, visual, or tactile cues: Audio Cues: Audio cues may include sounds, or voice messages recorded by the dreamer themselves.
Tactile Cues: This type of cue may include a pattern of vibrations. Visual Cues: These cues often include a series of flashing lights, delivered via LED lights built into the mask. Lucid dreaming techniques include: Reality Checks: During the day, a person repeatedly asks themselves if they are awake. This helps them get in the habit of being able to distinguish whether they are awake or asleep.
It refers to purposeful sleep interruption in which the person wakes up and goes back to sleep within 30 minutes to two hours. Lucid dreaming has been studied extensively, but much is still unknown about the phenomenon.
Some researchers believe activity in the prefrontal cortex of the brain is related to the development of lucid dreams. During non-lucid dreams, people are cognizant of objects and events within the dream state, but they are not aware of the dream itself and cannot distinguish being asleep from being awake. This has been attributed in part to lower levels of cortical activity. Lucid dreams are different because sleepers are aware they are dreaming and, in some cases, can exert control over their surroundings.
Some studies have linked these characteristics to elevated cortical activity. In sleepers who have been observed during lucid dream studies, prefrontal cortex activity levels while they are engaged in lucid dreaming are comparable to levels when they are awake.
While normal dreams can occur during different stages of the sleep cycle , studies have shown most lucid dreaming takes place during rapid eye movement REM sleep. REM sleep constitutes the fourth and final stage of a normal sleep cycle; the first three stages consist of non-rapid eye movement NREM sleep.
The general consensus among researchers today is that lucid dreams originate from non-lucid dreams during the REM sleep stage.
In this sense, lucidity is an aspect of dreams that can be triggered using different means. Spontaneous lucid dreams are rare and difficult to foresee. To study these phenomena, researchers typically induce lucid dreams using different methods. Some of the most common techniques include the following:. Additionally, some studies have involved inducing lucid dreams using certain types of drugs and supplements.
For some studies, subjects are asked to make specific eye movements while sleeping to signal they are having a lucid dream. EOGs are particularly helpful for detecting these movements. The popularity of self-induced lucid dreams has grown in recent years. The most common reasons for inducing lucid dreams include wish fulfillment, overcoming fears, and healing.
Some studies have also shown a link between inducing lucid dreams and overcoming the fear and distress associated with nightmares. Lucid dream therapy has shown to be largely ineffective for some groups, such as people with post-traumatic stress disorder. Some researchers have introduced another problem with lucid dreams: they are potentially disruptive to sleep. Since lucid dreams are associated with higher levels of brain activity, it has been suggested these dreams can decrease sleep quality and have a negative effect on sleep hygiene.
Additionally, people with narcolepsy — a sleep disorder characterized by excessive daytime sleepiness and irresistible sleep attacks — are more likely to experience frequent lucid dreams.
The study of lucid dreams is fairly new and largely incomplete. More research is needed to better understand these types of dreams and pinpoint why some people are predisposed to more frequent and intense lucid dreams. Triggering lucid dreams can be fairly easy with the right methods. Those who are inexperienced with these phenomena may be able to induce a lucid dream for themselves through the following means:.
Other techniques may be used to induce lucid dreams. These include transcranial direct current stimulation tDCS , which painlessly applies electrical currents to different areas of the brain, and certain types of medications. There is little scientific research to demonstrate the effectiveness of these methods. Maybe you want to fly or fulfill a sexual fantasy. Whatever it is, focus on that thought as you drift off to sleep. In the lucidity world, this practice is called predetermination , and it will help increase your chances of entering into a dream that you are then able to experience and control in ways you desire.
