You’ve probably heard the old tale—eating cheese before bed causes strange dreams. Maybe you’ve even experienced it yourself: an unusually vivid, cinematic, or downright bizarre dream after a late-night snack. But could there be any truth to this culinary folklore? And more importantly, can what you eat really influence your brain’s ability to dream creatively or solve problems overnight?
As it turns out, there’s growing evidence that food affects more than just your waistline—it can also influence how your brain behaves during sleep. From neurotransmitter regulation to the timing of your sleep cycles, your diet plays a behind-the-scenes role in your brain’s most imaginative hours.

What Are “Cheese Dreams,” Really?
The phrase “cheese dreams” has been around for decades, suggesting that dairy—especially cheese—may lead to more vivid, strange, or unsettling dreams when consumed close to bedtime. But is there any science to support this? Surprisingly, there just might be.
The British Cheese Board Study
In 2005, the British Cheese Board conducted a small (and not peer-reviewed) study where participants consumed different types of cheese before bed. The results were quirky but suggestive:
- Stilton cheese: Produced dreams described as “bizarre” and “hallucinatory.”
- Cheddar: Led to dreams involving celebrities.
- Red Leicester: Was associated with nostalgic or childhood dreams.
While the study was informal, it sparked public fascination and opened the door to deeper questions about how specific nutrients might interact with brain chemistry during sleep.
How Food Affects the Sleeping Brain
To understand how your midnight snack might influence dream content or creativity, we need to explore the brain’s chemistry during sleep—especially REM sleep, the stage most closely linked with vivid dreaming and creative insight.
Neurotransmitters in Sleep and Dreaming
- Serotonin: Influences mood and helps regulate sleep cycles. Its precursor, tryptophan, is found in many protein-rich foods like cheese and turkey.
- Acetylcholine: Crucial for REM sleep. Certain foods and herbs (e.g., eggs, soy, ginkgo) may influence acetylcholine levels.
- Dopamine: Involved in dream intensity and emotional tone. Its activity during REM can make dreams feel more meaningful or dramatic.
Eating foods that influence these chemicals may shift the tone, content, or frequency of your dreams—and potentially boost your brain’s creative potential while you sleep.
REM Sleep: The Brain’s Creative Workshop
Rapid Eye Movement (REM) sleep is when most dreaming occurs. During REM:
- The brain is highly active, almost as much as when you’re awake.
- The prefrontal cortex (responsible for logic and restraint) is less active.
- The limbic system (emotion, memory, imagination) lights up.
This cocktail of high emotion and loosened logic creates ideal conditions for divergent thinking—the same kind used in artistic expression, storytelling, and breakthrough problem solving.
Problem-Solving During Sleep
There are many documented cases of people waking with solutions to complex problems. Paul McCartney claimed he dreamt the melody to “Yesterday.” August Kekulé reportedly saw the ring structure of benzene in a dream. While diet wasn’t part of these stories, their dreams occurred during a mental state that can be influenced by food.
Foods That May Boost Creative Dreaming
Here’s a list of dietary components that could support more vivid or creative sleep thinking:
1. Tryptophan-Rich Foods
- Examples: Cheese, turkey, eggs, tofu, seeds
- Helps boost serotonin, supporting smoother sleep cycles and potentially vivid dreams
2. B Vitamins
- Examples: Whole grains, dairy, leafy greens, bananas
- Essential for neurotransmitter synthesis and may support memory integration during REM
3. Healthy Fats
- Examples: Nuts, avocados, olive oil, fatty fish
- Support brain plasticity and cellular communication, which could enhance dream fluidity and insight
4. Herbal Sleep Aids
- Valerian root, chamomile, lemon balm
- May increase the likelihood of REM by promoting relaxation and longer sleep duration
Cheese and Nighttime Creativity: Coincidence or Correlation?
While cheese alone won’t turn you into a dreaming Da Vinci, there are plausible reasons why dairy—especially before bed—could impact sleep thinking:
- High protein and fat content slows digestion and provides a steady energy release during sleep.
- Calcium and tryptophan help synthesize melatonin and serotonin, both key to sleep regulation.
- The psychological expectation of cheese causing dreams may create a self-fulfilling effect.
Can Food Actually Enhance Creativity During Sleep?
There’s no magic snack that guarantees a midnight epiphany, but certain eating habits can foster the conditions for rich mental processing overnight. Here’s how to create a dream-fertile foundation:
Tips for Sleep-Enhanced Creativity
- Eat light, but not on empty: Going to bed too hungry or overly full can disrupt sleep quality.
- Include sleep-supportive nutrients: Think magnesium, tryptophan, and B vitamins.
- Avoid stimulants: Sugar, caffeine, and alcohol can interfere with REM and dream clarity.
- Keep a dream journal: Writing down dreams reinforces the brain’s attention to its own creative output.
- Reflect on questions before bed: Asking yourself a creative question can prime the brain to “solve” while dreaming.
Sleep, Snacks, and Surreal Solutions
While cheese dreams may still live partly in the realm of folklore, the broader truth is clear: your brain’s nocturnal adventures are closely tied to your waking choices—including what you eat. Nutrition influences sleep architecture, neurotransmitter activity, and ultimately, the quality of your nighttime cognition.
So whether you’re a dream journaler, a midnight snacker, or a problem-solver in your sleep, remember: your brain keeps working while you rest—and with the right fuel, it might just dream up something brilliant.
