Throughout human history, dreams were regarded as a sign of what might happen in your life and the world.

Today researchers are learning more and more about how sleep and the brain control your dreams. The human brain is wired to do many things during the stages of sleep.

We now understand different types of dreams and classify them into categories.

Lucid dreaming is a term scientists use to describe when you know the situation you are experiencing, is in fact, a dream. It’s a scenario with exciting possibilities.

Being able to control your dreams may have many benefits. These may include:

• Learning and integrating new skills
• Reversing mental health conditions
• Curing nightmares
• Reversing PTSD
• Reverse sleep disorders

Neuroscientists now understand the chemistry of dreams and how you can use specific supplements to trigger lucid dreams.

Research has investigated a supplement called galantamine to treat Alzheimer’s disease. It acts on enzymes that break down a neurotransmitter  known to trigger dreams during sleep.

Brain conditions like Alzheimer’s disease associate with sleep disorders. Even a few nights of sleep deprivation can increase the build-up of Amyloid plaques in the brain, that contribute to mental decline. (1)

However, new studies show galantamine may also trigger a lucid dream.

In this article, we’ll explore:

1. The brain chemistry of what causes lucid dreaming
2. The study that used galantamine to trigger lucid dreams
3. How to use Galantamine to trigger a lucid Dreams

Why do Dreams Happen in REM Sleep?

Let’s take a quick look at the neuroscience of sleep and dreams.

In mammals and birds, sleep is split into two types:

1. Non-Rem Sleep (NREM) – Deeper sleep when the brain directs cleansing of the bodily organs (eg. Digestive system). Slower deeper brain waves (Delta waves) occur in these phases.
2. REM (Rapid Eye Movement) – When the brain undergoes self-cleansing. Faster brain waves (Beta Waves) are recorded that are similar to wakeful brain waves.

We now know that most dreams occur during REM sleep. During this period, the brain is doing ‘self-work’ like removing build-up from the day.

Brain waves during REM sleep are faster, similar to waking hours, than those during NREM sleep.

Understanding the stages of sleep tells us that dreams could be a good indicator of healthy sleep.

If you don’t dream, then it might mean you’re not getting enough, or good quality REM sleep.

What Causes Lucid Dreaming?

If you’re new to Lucid dreaming, you can read this article: What is Lucid Dreaming?

It’s now understood that specific types of neurotransmitters manage the sleep cycle.

Acetylcholine (ACh), is a neurotransmitter known to induce the REM sleep cycle. The more ACh in your brain, the more likely that you’ll trigger lucid dreaming.

Scientists have studied the brain receptors for (ACh).

These include:

• Acetylcholine receptors: Chrm1 and Chrm3

They removed the genes that regulate these receptors in mice. The result was less REM sleep in the study group.

How to Trigger Lucid Dreaming with Galantamine

One method to trigger lucid dreaming is to prevent the breakdown of ACh in the brain.

By using a drug or supplement called galantamine, scientists found they were able to trigger lucid dreaming.

The supplement was approved by the FDA in 2001.

Studies on galantamine have found: (3)

• Improvement in both short and long-term memory
• Reduction symptoms of Alzheimer’s disease
• Effective in treating mild to moderate dementia

Galantamine increase ACh levels in the brain. It seems to improve higher memory allowance, which improves dream recall as well as the ability to lucid dream.

What is Galantamine?

When neurotransmitters are released, the body uses them and or breaks them down. Inhibitors stop the action of a particular neurotransmitter or enzyme.

Galantamine is a natural supplement:

• It’s an alkaloid isolated from bulbs of a variety of flowers
• Found in daffodils and red spider-lily’s.
• As a chemical, it is an Acetylcholinesterase inhibitor (AChEls).

Galantamine inhibits the enzyme that breaks down ACh. It hence increases the amount of ACH present in the brain.

These mechanisms explain why it may help improve REM sleep and lucid dreaming.

Galantamine is known to have powerful mind-inducing effects. It may even be regarded as a Nootropic (brain-enhancer).

It belongs to a class of substances frequently reported with the side effect of an increase in the vividness or intensity of dreams.

REM Sleep and Triggering Lucid Dreaming

A 2018 double-blind, placebo-controlled, crossover study looked at galantamine and lucid dreaming. (5)

What they did:

• 121 participants (63 males, 58 females)
• 3 consecutive nights
• Used sleep interruption roughly around the third REM cycle in the night
• MILD technique (a lucid dreaming technique)
• Each subject was given a random packet containing 0 mg, 4 mg, or 8 mg of galantamine

Dreams were classified as:

1. None
2. DILD (dream-initiated lucid dream)
3. WILD (wake-initiated lucid dream)

The results:

• 62% reported one or more lucid dreams
• 57% on one or more nights with galantamine
• 42% with the 8 mg galantamine dose
• 27% with the 4 mg galantamine dose
• 14% with the active placebo procedure

A total of 69 out of 121 participants (57%) successfully had a lucid dream on at least one out of two nights on an active dose of galantamine.

How to use Galantamine to Trigger Lucid Dreaming

Always check with your physician before starting a supplement or medication.

• Lucid Dreaming Dosage:

The most common dosage for lucid dreaming is 4-8mg. It might be best to start with 4mg, record your results, and increase to 8mg if needed.

Here are a two different galantamine supplements with 4mg and 6mg options.

Galantamine supplements: 4mg

Galantamine supplements: 6mg

• Technique and how to take galantamine as a sleep supplement:

Take the pill after 4-6 hours of sleep – it will gain its highest activity in an hour. Set an alarm between 3-4am, take the pill, and go straight back to sleep

• What happens in lucid dreams?

As you enter the stage between wakefulness and sleep, (hypnagogia) you may experience hallucinations.

1. Random speckles
2. Geometric patterns or lines
3. Monochrome patterns or rich colors
4. Still or moving patterns
5. Flat or three-dimensional shapes

If you see these, stay as still as possible, it’s likely you’re entering a lucid dreaming state.

What Happens in Lucid Dreams, and are there Dangers?

Always check with your physician and ask about interactions with medications you’re taking.

If you’re new to lucid dreaming read this blog before taking any medication or supplement. What is Lucid Dreaming?

Danger or side-effects may include:

• Being unable to discern between reality or dreaming
• Sleep paralysis

How do I Trigger a Lucid Dream with Sleep Techniques?

1. Practicing mindfulness and meditation

Meditation is likely to increase your chances of lucid dreaming.

During the day, or even right before going to sleep, meditate for at 10-15 minutes.

Here are a few resources and explanations for beginners.

• Meditation for mindfulness
• 6-Step Healing Meditation
• Meditation for higher consciousness

2. Good Sleeping Patterns

Good sleeping patterns mean balancing melatonin levels released from the pineal gland.

These depend on:

• removing artificial light in the night
• getting daily and morning sunlight
• breathing deeply through the nose all night
• good sleep hygiene
• healing the pineal gland
• Promote REM sleep:

If you feel REM Sleep or lucid dreaming starting, try to be as still as possible. This allows your body to enter sleep paralysis. It’s this stage that the brain immerses itself in the world of rapid eye movement sleep.

Conclusion

The benefits of lucid dreaming are now being understood to include better memory, focus, learning, and healthy sleep.

With proper REM sleep cycles, the brain may reduce the risk of conditions like Alzheimer’s disease, and dementia.

Galantamine whilst approved as treatment for Alzheimer’s disease may also be effective to trigger lucid dreaming.

For better sleep use with meditation and mindfulness practices.

Now it’s up to you.

The post New Study Reveals Alzheimer’s Supplement Can Trigger a Lucid Dream appeared first on .

Neuroscientists are revealing the many different types of dreams. One type, called lucid dreaming, is a feeling that a dream scenario is real-life. 

That means you’re dreaming but you know it. You could also call it self-realization dreaming.  

Research suggests two of the most common types of lucid dreams are trying to fly, and having sex. If you’ve ever had either of these dreams, and been aware that you’re actually not flying (or having sex), then you could be a lucid dreamer. 

So what is lucid dreaming?  

In this article we’ll explore the different types of dreams and the techniques for lucid dreaming.  

What happens when you lucid dream?  

Lucid dreaming is a dream where you are in a scenario that you KNOW is a dream. People report many different experiences from lucid dreaming. 

Scientists are discovering new results on lucid dreaming.

One study surveyed 570 people who said they’ve experienced lucid dreaming to find the most common lucid dreams. Researchers asked whether dreamers decided what they were going to do in their dream.  

Results show a variety of types of lucid dreams.

These include:  

• Problem-solving dreams 
• Dreams of experiences not possible in real life 
• Near-death experience dreams
• Dreams of solutions to reoccurring nightmares 

Lucid dreaming also could be helpful in treating psychological problems such as frequent nightmares or PTSD. A previous survey of about 300 lucid dreamers found that the majority of lucid dreamers used their dreams to have fun and to change nightmares into pleasant dreams. About 30 percent of lucid dreamers also reported using lucid dreams for problem solving and creativity. 

What are the causes of dreaming? 

To this day, we don’t fully understand why we dream. Because some aspects of the brain work similarly when asleep and when awake, many believe that dreams aren’t exactly random. For example, it’s been observed that when we’re asleep, our brains capture information from our immediate environment and find ways to incorporate that into whatever dream we’re having.  

Some also theorize that dreams pull from our memories as well, using them as a sort of foundation upon which the dream is built.

The different types of dreams 

Lucid dreaming is just one type of dream.  

Dreaming has only recently become a full area of study for scientists. There are many classifications for dreaming. Some say that there are eight or nine types of dreams, while others are less specific.  

However, many experts agree that in general, dreams can be classified into three types.

1. Normal dreams: During these kinds of dreams, we are not aware that we’re dreaming. We see, hear, feel, and experience things, and think that we’re actually moving in our reality.
2. Nightmares: Nightmares are like normal dreams, except they evoke severely negative emotions and are regarded as extremely distressing and unpleasant. They happen when the amygdala, the part of the brain associated with anger and fear, kicks into overdrive. Understandably, waking up from a nightmare is often accompanied by a tidal wave of relief.
3. Lucid dreaming: As there’s the added element of the dreamer being aware that they’re actually in a dream, lucid dreaming tends to involve a more complex thought process, and can be quite detailed. Furthermore, some lucid dreamers have attested to the fact that they retain part of the dream in their memory upon waking up. In fact, for some, these memories feel so real that they have slight difficulty accepting that they didn’t happen in the real world. 

The question now is this: How do we enter the state of lucid dreaming?  

Lucid Dreaming & Stages of Sleep 

Lucid dreaming requires the brain to entire the full cycles and stages of sleep. Source

To understand how to lucid dream we need to know the stages of sleep: 

There are typically four stages of sleep, each lasting between 5 to 15 minutes. An entire sleep cycle — all of these stages together, repeated a couple of times — lasts between 90 to 110 minutes. 

1. Stage 1: This is the beginning of non-rapid eye movement (NREM) sleep. This also marks the start of light sleeping. At this stage, you can easily be jolted awake by the slightest disturbance (such as a loud sound in your environment or a few light taps on your shoulder). At this stage, your brain activity starts to slow as your muscles relax. 
2. Stage 2: At this stage, you’re not as easy to wake, but you’re not quite in dream world yet. Here, your heart rate begins to slow, as your body temperature goes down. Your brain waves also begin to decelerate, save for brief, rapid activity known as sleep spindles and brain waves called K-complexes (which are said to suppress cortisol arousal and help memory consolidation while sleeping). 
3. Stage 3: Also known as deep NREM sleep, this is the stage where you become less likely to be awoken by simple physical disturbances or arousals. This is said to be the most restorative stage of sleep, and is also where sleepwalking or sleep talking take place. 
4. REM Sleep: This is where most dreaming occurs. Brain waves are more active here than in the previous two stages, and it’s easier to wake you up during this stage. 

Rapid-Eye Movement (REM) is the state in which the brain functions as if it were awake, but while the eyes flutter and move at an accelerated rate. It originates from the pons (the base of the brain), traveling all the way to the thalamus and the cortex. According to experts, this occurs in 90-minute cycles, establishing neural pathways and basically “writing” memories.  

Additionally, the body produces cortisol, the stress hormone in charge of maintaining your immune system and blood glucose levels, during this REM state. Levels of dopamine, the hormone connected with pleasure, rise as well, facilitating the continuation of the dream state. 

Brain Waves and Dreams   

Brainwaves are rhythmic electrical pulses of neural activity in the brain. They signal how neurons communicate with one another.  They’re categorized based on their bandwidths (measured in Hertz)  in order to determine their function: the slower brainwaves are larger, while the faster brainwaves are a bit more subtle.  

Our brainwaves also adapt based on our current circumstances. For instance, we experience slower brainwaves when we’re tired and not at peak operating efficiency; on the other hand, when we’re at heightened alertness, higher-frequency brainwaves become more prominent. 

There are different types of brainwaves: 

• Infra-low waves (<0.5 Hz): While they are regarded as the basic cortical rhythms in our brain, we know extremely little about them, due to the fact that they are quite difficult to detect and measure.  

• Delta waves (0.5 to 3 Hz): These are the slowest and loudest brainwaves, detected in NREM sleep and deep meditation. 

• Theta waves (3 to 8 Hz): Typically detected during deep meditation and sleep, theta waves are said to be the “gateway” to memory, intuition, and learning. They tend to occur during that brief, fleeting point between being awake and falling asleep. 

• Alpha waves (8 to 12 Hz): Dominant during the brain’s resting period, alpha brainwaves play an important role in alertness, calmness, learning, and mental coordination. 

• Beta waves (12 to 38 Hz):  These are the brain waves observed when we’re awake. These register when we are alert, thinking, making decisions, or generally just being aware of our surroundings. 

• Gamma waves (38 to 42 Hz): The fastest of brainwaves, gamma waves were initially regarded as nothing more than “spare brain noise.” Subsequent research, however, has revealed that gamma waves are actually involved in processing information from different areas of the brain simultaneously. They were also observed to be especially active during the states of the “higher virtues” such as altruism and love. Though the origin of gamma waves remains unknown, experts say that they actually play a key role in modulating consciousness and perception. 

Which Brainwaves Achieve Lucid Dreaming?  

Research shows certain brainwaves are associated with dream types.

• Gamma Waves  

In 2009, a team of lucid dream researchers from the Neurological Laboratory in Germany detected gamma waves at 40 Hz in lucid dreamers.  

They were looking into how the brain’s physiology changes during lucid dreaming, on the premise that lucidity is a “dissociated state” somewhere between dreaming and the state of being awake.  

They noted that the effect was most apparent in the frontal and fronto-lateral areas of the brain. Incidentally, these are the areas of the brain where higher awareness and linguistic thought are believed to be centered. Since lucid dreaming can be interpreted as a person’s capacity to take control of their own dreams, this does make sense. 

• Theta brainwaves 

Theta brain waves are best described as a state of true relaxation. These are the brain waves a person will experience when they’re in the REM state of sleep, or they are deep in hypnosis. They help you achieve a state of mindfulness, which may assist lucid dreaming.  

Ultimately, as you progress through the sleep stages and achieve a relaxed state, you move closer towards the state of lucid dreaming. Being in control of what happens in your dream — essentially, creating your preferred reality in your dream world — requires access to your memories. Hence, that’s where the theta brainwaves play a role. 

How Sound Can Control Brainwaves: Binaural beats 

Scientists have noticed that brainwaves can be affected or altered by exposure to soundwaves (otherwise known as brainwave entrainment, or binaural beats). They believe that the soundwaves create brainwave shifts that result in slower frequencies (and thus, deeper states of relaxation). 

A recently conducted study with 19 participants revealed that exposure to binaural beats had a noticeable impact on three key hormones for sleep. 

1. Sixty-eight percent of the participants registered an increase in DHEA, a critical hormone for immunity and disease protection that suppresses cortisol. 
2. Meanwhile, 73 percent of the participants had higher levels of melatonin, the sleep-promoting hormone, post-binaural exposure. 
3. Last but not least, 70 percent of the participants registered reduced levels of cortisol after binaural beat exposure. 

Additionally, a separate study from 2017 revealed that a combination of binaural beats and visual stimulation helped in reducing patients’ perception of acute pain. Other studies have revealed that they affect chronic pain perception as well. And of course, the less pain you feel, the easier it would be for you to fall asleep. 

How to Control Your Dreams

One study looked at different groups to achieve lucid dreaming.  

Three techniques were tested among 169 participants divided into three groups.  

• The first group was assigned to do reality testing — they had to go through their day figuring out whether they were asleep or awake. 
• The second group was assigned to do the WBTB (wake back to bed) technique — they slept for 5 to 6 hours, stayed awake for 10 minutes up to an hour, and then went back to sleep. 
• The third group was instructed to try MILD (mnemonic induction of lucid dreams). They set their minds to entering the lucid dreaming state by repeating a mantra before sleeping.  

The third group proved to be the most successful. Approximately 17.4 percent of the time, the technique worked.  

The chances of success increased to almost 50 percent when participants dozed off within the first 5 minutes. 

Are there Dangers of Lucid Dreaming?  

However, lucid dreaming isn’t without its risks. Here are some reported side effects of lucid dreaming.

1. Sleep paralysis. When you’re in a state between dreaming and waking, you may be unable to move, despite experiencing the visions in your dream. This experience can be terrifying but is not really that common. 
2. Realistic experiences. The lucid dream may feel so realistic that it’s nearly indistinguishable from reality. While it’s bound to stop when you wake up–and you certainly won’t sustain any physical injuries you experienced in your dream–it doesn’t mean that you won’t be affected by any negative emotions that you felt while in the dream state. 
3. Dream claustrophobia. There’s also a chance that the lucid dream will be so vivid that you’ll feel that you can’t awaken from it or control it. Fortunately, like the other two, this stops when you wake up. 

In essence, think of lucid dreaming as an immersive and highly engrossing video game, with all the perks and pitfalls that come with such an experience. 

6 Ways to Control Lucid Dreaming 

With the balance of evidence, and much that we don’t know about lucid dreaming, here are 5 ways to attempt to access lucid dreaming.

1. Practice mindfulness daily. These promote higher frequency brainwaves that may give access to lucid dreaming. 
2. Set an intention to dream about a particular topic that is important to you.
3. Practice meditative breathing techniques 30 minutes before bed. Alternative nostril breathing may help to relax the brain and balance right and left-hand sides of the brain.  
4. Repeat a mantra associated with your dream. For example “I want to face my fear of heights”.  
5. Take a Galantamine supplement. A natural substance found in flowers such as Golden Spider Lily. It has been used in ancient Chinese culture for memory enhancement and is even a prescribed medication for Alzheimer’s disease and dementia.
6. Deep breathing before and as you sleep will help the brain progress through sleep cycles adequate for lucid dreaming.  

Conclusion 

Today we are on the brink on understanding the phenomenon of lucid dreaming. Achieving advanced states of awareness during sleep could prove to be a remedy for sleep disorders, PTSD, or to help people achieve higher states of consciousness.
