The Curious Case of Sleep Position and Dreams

Do you wake up in a cold sweat, heart racing, convinced that your seventh-grade Phys. Ed. teacher is perched on top of her car, leering at you with a malevolent gaze? If you are disturbed by that recurring nightmare, maybe you should reconsider how you position yourself as you are getting ready to slip into slumber. According to a 2004 study that possibly has not made its way onto your “must read” list, your choice of sleep position might play a role in how peaceful (or not) your dreams are.

Dreams — and nightmares — are so significant that they can shape history (as we explain in this article). That’s why this is such an Important topic. The study suggests that people who sleep on their left side are more likely to experience nightmares than those who favor their right.

Grab a cup of coffee, rub the sleep from your eyes, and join us as we try to explain the reasons for your memory foam mattress journeys.

The Numbers: Left vs. Right (and a Very Small Sample Size)

Before you flip your mattress to see if the other side is nightmare-proof, let’s dive into the details. The study, published in the Sleep and Hypnosis Journal for Cognition, Brain Health, and Nootropics, surveyed a whopping 63 people. Admittedly, not exactly a crowd, but how easy can it be to get people to volunteer to sleep while a lab coat-attired researcher stands by the bed, making notes on a clipboard? (which reminds us of this creepy sleep study that you might want to check out). Of these, 41 preferred their right side, and 22 were left-side snoozers. The findings? A startling 41% of left-side sleepers reported having nightmares, compared to just 15% of right-side sleepers.

Of course, with a sample size that small, these numbers could be more of a statistical coincidence than a universal truth. Still, the left-side nightmare conundrum has intrigued enough people to spark conversation two decades later. And isn’t that what all good research is about?

How to Turn Nightmares into Sweet Dreams

If you’re prone to nightly visits from your worst fears, don’t worry—your sleep position might not be the only culprit. There are some steps you can take to reclaim your nights and make them a little less Freddy Krueger and a little more fluffy kittens. Here’s how:

1. Be the Hero of Your Dreams

Before you drift off, remind yourself that you’re in control. Believe it or not, this little pep talk can help you steer the narrative if you find yourself in a nightmare. Dreaming of a scary clown? Picture yourself pulling out an oversized water balloon to defeat it—dream logic works in your favor here.

2. Write It Out

Sometimes the key to understanding your nightmares is putting pen to paper. Write down what you remember and look for patterns. That recurring dream where you’re being chased? It might be your brain’s not-so-subtle way of telling you something about your waking life.

3. Talk It Over

If your nightmares are persistent, a professional can help you get to the root of the issue. Sometimes, understanding why your brain is going to dark places is the first step to redirecting it toward something brighter—like an all-you-can-eat buffet dream scenario.

The Final Snooze

So, should you immediately roll over to the right side and hope for a Disney-level dream sequence? Maybe, but don’t lose sleep over it (see what we did there?). The study, while fascinating, is far from definitive. What matters more is finding a sleep routine that works for you and taking steps to manage any stressors or anxieties that might be sneaking into your subconscious.

Sweet dreams, whether you’re a left-sider or a right-sider. Those of us who sleep on our stomachs will try to hide our feelings of smugness while we await your report of your experience.
