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. These techniques are also only conducted in controlled clinical laboratory settings and should never be attempted by an individual unless under the supervision of a doctor or another credentialed medical or psychological professional.

Lucid dreaming is different for everyone.
Although people often go through a similar pattern, it is hard to guess when someone will master it. To start lucid dreaming frequently, and multiple times per week, it may take much longer — between months, up to a year. Once you master lucid dreaming, you will be able to lucid dream at will, to do almost anything you want, nearly every time you want! There is a difference between a vivid dream and a lucid dream. Sometimes, the self-awareness is combined with dream control, but now always.
So, if you are lucid inside the dream, but you have no control over it — it is still a lucid dream. As long as you know that you are dreaming inside a dream — you are lucid dreaming. Without this sense of awareness, you probably are not experiencing a lucid dream. In Dream Initiated Lucid Dreams , the moment you become lucid is when you suddenly realize you are dreaming.
In Wake Initiated Lucid Dreams , is when you jump right into a dreaming state from a waking state. However, the good news is that the odds are in your favor — especially if you are committed to trying.
In this research, the collected data for 50 years found that:. Consistent and sustained practice is vital in developing any new skill. As mentioned, lucid dreaming means awareness inside the dream , and it is not always accompanied by cream control. Every mind is different, so controlling lucid dreams comes easily to some people but poses a challenge for others.
Dream control might come with time and practice. Your intention matters the most and how much awareness you possess. Remember that it is possible never to reach full control. As a start, try to work within the logic of your unconscious mind. For instance, try changing the scenery when walking through a door.
Lucid dreaming specialists believe that anyone who has regular dreams can learn how to lucid dream. For some, it might come more naturally, and for others, it might be harder. But all in all, it is a matter of bringing waking awareness inside the dream. There are a few things you can do throughout your daily life to encourage lucid dreaming at night:. Dream journals are the best way to improve your dream recall and to experience intense and vivid dreams. Keep a notebook beside your bed and write down your dreams as soon as you wake up.
Write your dreams down even if you rise in the middle of the night.
