Sleep is vital for human creativity. Many scientific studies have explored the links between sleep, dreams, and creativity, with a focus on the REM sleep stage, when deep dreaming occurs. However, recent research has shifted attention to the earliest stage of sleep, known as N1 or hypnagogia, a semi-lucid state between wakefulness and sleep. This stage has been associated with enhanced creativity and problem-solving abilities.
The MIT News Office reported on a study conducted by researchers from MIT and Harvard Medical School, which found that people are more creative after waking from the earliest stage of sleep. The study used a device called Dormio to track and influence sleep patterns. Participants who were prompted to dream about specific topics during the N1 stage exhibited increased creativity in subsequent tasks.
Additionally, the importance of REM sleep for creativity has also been highlighted. REM sleep is characterized by high excitation, plasticity, and connectivity, providing an ideal environment for forming novel connections and integrating memories.
The relationship between sleep and creativity is complex, and further research is needed to fully understand the role of different sleep stages in enhancing human creativity.

What You'll Learn
REM sleep and non-REM sleep have different effects on creativity
Sleep is vital for creativity, and the different stages of sleep have varying effects on it. The earliest stage of sleep, N1 or hypnagogia, is a semi-lucid state where we start dreaming before falling unconscious. During this stage, the brain makes more wide-ranging connections between disparate concepts, boosting creativity.
REM sleep, which is characterised by rapid eye movement, high cortical acetylcholine, and low synchrony between the hippocampus and neocortex, is important for creative problem-solving. The high excitation, plasticity, and connectivity in this sleep stage facilitate the formation of novel, unexpected connections within existing knowledge frameworks. REM sleep may also promote the removal of unnecessary constraints on problem-solving, allowing for more creative solutions.
Non-REM sleep, on the other hand, is crucial for processing and forming memories of information encountered during the day. It stabilises individual experiences and associations, laying the foundation for creative insights. Non-REM sleep is also associated with gist abstraction, where the brain extracts overarching rules and commonalities from related memories.
The interleaving of REM and non-REM sleep across the night likely plays a critical role in enhancing creative problem-solving abilities. The two sleep stages have complementary functions, with non-REM sleep abstracting rules and commonalities, and REM sleep forming novel associations and restructuring knowledge frameworks.
Research supports the positive impact of sleep on creativity. Studies have shown that a short nap can improve performance on creative challenges. Additionally, sleep deprivation has been found to impair creativity, with participants experiencing significant impairment in divergent thinking tasks after 32 hours of sleep deprivation.

The twilight period between wakefulness and sleep boosts creativity
The twilight period between wakefulness and sleep, also known as sleep onset, hypnagogia, or N1 sleep, is a semi-lucid state where vivid dreams begin. This state has been linked to enhanced creativity, with research suggesting that it acts as a "sweet spot" for creativity and problem-solving.
During sleep onset, individuals are in a hypnagogic state, where they begin to dream before fully losing consciousness. This state is characterised by vivid imagery, hallucinations, and dream-like thoughts. It is a unique mental state that lies between wakefulness and sleep, and it has been associated with enhanced creativity and problem-solving abilities.
Research has shown that a short nap or the act of drifting off to sleep can spark creativity. The MIT and Harvard University study found that participants who were prompted to dream about a specific topic during sleep onset performed more creatively on subsequent tasks. This phenomenon has been termed "targeted dream incubation," and it suggests that guiding dreams during this twilight period can enhance creative performance.
Additionally, the twilight period between wakefulness and sleep may be especially powerful for problem-solving. A 2021 study found that even 15 seconds of non-rapid eye movement sleep stage 1 (NREM1) sleep tripled the likelihood of finding a solution to a series of mathematical challenges. This effect disappeared if participants entered a deeper sleep stage, highlighting the unique potential of the twilight period for creative insight.
The link between sleep onset and creativity has been recognised by notable figures throughout history, including Thomas Edison and Salvador Dali. They are known to have taken advantage of this state by napping with a heavy object in their hand, which would drop and wake them as they drifted off, allowing them to harness any novel ideas or solutions from their early-stage dreams.
In conclusion, the twilight period between wakefulness and sleep, marked by the onset of N1 sleep, is a creative sweet spot. This state enhances the ability to form novel connections and think outside the box, making it an ideal time for creative tasks and problem-solving.

Lack of sleep negatively impacts creativity
Sleep is vitally important for creativity. However, a lack of sleep can significantly hurt this. Research has shown that not getting enough sleep can harm your creative ability.
A 1988 study showed that participants who went without sleep for 32 hours experienced significant impairment to their ability to perform on a divergent thinking test. Another study in 1992 replicated these results.
This shows that less than one single night of poor sleep can significantly lower your creativity. A 2014 study found that aspects of our brain involved in higher-order reasoning, like the prefrontal cortex, are especially susceptible to sleep deprivation. This may explain why sleep deprivation can so strongly affect creativity.
Research from the USA has shown that more than a third of adults are getting less than seven hours of the recommended sleep every night, and up to 70 million Americans have chronic sleep disorders.
So, if you're feeling uninspired, make sure you're getting a good night's rest. It might just help you get your next great idea.

The creative function of dreams
Dreams have long been associated with creativity. Artists, scientists, and entrepreneurs have often claimed that their dreams were the source of their best ideas. Dreams can be a space for creative, unexpected, and original thoughts. Recent scientific evidence has supported the link between dreams and creativity, showing that the earliest stage of sleep may be harnessed and guided to enhance creative thinking and problem-solving.
The Science of Dreams and Creativity
During sleep, our brains go through different cycles, including the well-known REM (Rapid Eye Movement) sleep, which is often associated with deep dreaming. However, recent studies have focused on the earliest stage of sleep, known as N1 or hypnagogia, a semi-lucid state between wakefulness and sleep where vivid dreams occur. This stage has been found to be a "sweet spot" for creativity, as the brain makes more wide-ranging connections between disparate concepts, providing a boost in creativity.
Targeted Dream Incubation
Researchers from MIT and Harvard have developed a technique called "targeted dream incubation," where individuals are prompted to dream about a specific topic during the N1 sleep stage. In one study, participants were asked to dream about "trees" and then performed creative tasks related to that theme. Those who were prompted to dream about trees showed significantly higher creativity scores than those who slept without the cue, suggesting that guiding dreams towards specific topics can enhance creative performance.
Historical Examples of Creative Dreams
Throughout history, there have been numerous examples of dreams inspiring creativity. For instance, Robert Louis Stevenson's "Strange Case of Dr Jekyll and Mr Hyde" was said to be inspired by a dream, and Paul McCartney discovered the tune for "Yesterday" in a dream. German chemist Friedrich August Kekulé stated that the idea for the ring structure of benzene came to him in a daydream, and Aphex Twin wrote music by sleeping in his studio and then recreating the sounds he heard in his dreams.
The Benefits of Sleep for Creativity
Getting a good night's sleep, including REM sleep, is essential for enhancing creative performance. Sleep facilitates insight, memory consolidation, and the integration of relational memories. It helps in reorganizing existing knowledge, forming novel associations, and solving problems. On the other hand, lack of sleep can impair creativity, with studies showing that sleep deprivation can significantly lower creative abilities.
In conclusion, the creative function of dreams is a fascinating aspect of human cognition. By understanding the link between dreams and creativity, we can harness the power of sleep to enhance our creative potential and solve complex problems.

The Dormio Device
The Dormio device is a glove that measures three physiological markers of sleep — changes in muscle tone, heart rate, and skin conductance — and communicates them to a smartphone or laptop app. As someone wearing the glove enters the N1 state, the app prompts them to dream about a specific topic. After a few minutes, when the wearer begins to enter the next stage of sleep, the app wakes them up, asks them to report what they were dreaming about, and records their response. The system then plays an audio cue, reminding the wearer to think of certain words, with the aim of integrating the cued topic into their next set of dreams. The user then drifts back to sleep, with the cue in mind.
Applications of TDI
TDI can be used to facilitate personal introspection, as hypnagogia is a state of mind that remains inaccessible during the day. It can also be used to open up new avenues for exploring the mind, as it allows for controlled experiments on how dreams and dream content influence cognition, including questions about emotion, creativity, memory, and more.
TDI may also be useful in the therapeutic domain, as it may give patients and clinicians a lever of control to gain insight via dreams and to combat nightmares, which can take a toll on people who struggle with anxiety and trauma. It can also be used for targeted creative brainstorming, as luminaries such as Sylvia Plath, Salvador Dalí, and Edgar Allan Poe have used their dreams to release creative potential.

Frequently asked questions
Sleep is known to be important for creative thinking, but there is a debate about which sleep stage is most relevant. REM sleep has long been linked with problem-solving and creativity. However, some studies have shown that non-REM sleep is more important for creativity as it is when the brain processes and forms memories, while REM sleep is when the brain makes new and unexpected connections with those memories.
REM sleep is associated with high levels of plasticity and connectivity in the brain, which provide an ideal setting for the formation of novel and creative connections.
Sleep deprivation has been shown to harm creativity. A 1988 study showed that participants who went without sleep for 32 hours had significant impairment in their ability to perform on a divergent thinking test.
There is no definitive way to get more REM sleep as it is one of the sleep stages that we have little control over. However, you can try to improve your sleep quality and duration in general, which may result in more REM sleep.
