You’re half-asleep. The room is quiet. Suddenly, a weirdly perfect melody or a bizarrely logical solution to that work problem you've been chewing on just... appears. It feels like a gift. People often post online with the phrase this occurred to me in a dream, usually followed by a shitpost or a world-endingly funny meme, but there’s a massive psychological engine chugging away behind that curtain. It isn’t just randomness.
Dreams are basically the brain’s way of filing taxes while high on its own supply of neurotransmitters.
When you sleep, your prefrontal cortex—the part of the brain that tells you "don't say that, it's stupid" or "that's physically impossible"—goes offline. It takes a break. Without that internal critic, your neurons start making connections that would never happen during a caffeinated Tuesday afternoon. It’s why so many legendary breakthroughs in science and art start with someone waking up and scrambling for a pen.
Honestly, the "this occurred to me in a dream" phenomenon is more than just a TikTok trend or a Reddit trope. It's a peek into the hypnagogic state and REM cycles where the brain performs "associative splays." It’s messy. It’s weird. It’s often useless. But when it works? It changes everything.
The Science of Why This Occurred to Me in a Dream Makes Sense
Deirdre Barrett, a psychologist at Harvard Medical School, has spent a huge chunk of her career looking at how we solve problems while we’re out cold. Her research suggests that dreaming is essentially just "thinking in a different biochemical state."
Think about the structure of the brain during REM sleep. Your levels of norepinephrine drop. That’s the chemical linked to focus and stress. When it’s gone, your focus widens. You stop looking at the "obvious" path and start seeing the weird side-alleys of logic.
There was a famous study back in 2004 published in Nature where researchers gave participants a complex math string to solve. There was a hidden rule—a shortcut—that made it easy. The people who were allowed to sleep were over twice as likely to "gain insight" into the shortcut than those who stayed awake. Their brains did the heavy lifting while they were busy dreaming about giant squirrels or whatever.
It's not magic, it's memory consolidation
When you say this occurred to me in a dream, you’re describing the end result of memory consolidation. Your hippocampus and neocortex are having a conversation. They're deciding what to keep and what to trash. During this "data transfer," fragments of different memories collide.
If you’ve been staring at a coding error for six hours, your brain has those fragments at the top of the pile. In sleep, it might pair that coding error with a visual memory of a plumbing leak you saw three years ago. Suddenly—boom—the logic clicks. You realize the "leak" in your data flow is a logic gate issue.
Famous Examples That Weren't Just Memes
We see the "this occurred to me in a dream" meme used for things like "a movie where Muppets reenact the French Revolution," but history is littered with high-stakes versions of this.
- Dmitri Mendeleev and the Periodic Table: He had been struggling to organize the elements. He reportedly fell asleep at his desk and saw a table where all elements fell into place as required. He wrote it down immediately upon waking. Only one correction was needed later.
- Paul McCartney and "Yesterday": He woke up with the tune in his head and spent weeks asking people if they’d heard it before. He thought he was accidentally plagiarizing someone else because the melody was too "complete" to have just appeared.
- Mary Shelley’s Frankenstein: She had a "waking dream" of a pale student of unhallowed arts kneeling beside the thing he had put together.
These aren't just myths. They are documented instances of the brain utilizing low-inhibition states to finalize complex creative tasks. It’s why "sleeping on it" is actually some of the best professional advice you can get.
The Viral Culture of the "Dream Reveal"
In the last couple of years, this occurred to me in a dream became a linguistic shorthand on platforms like X (formerly Twitter) and Tumblr. It’s a way to bypass criticism. If you post a bizarre idea and lead with "this occurred to me in a dream," you’re telling the audience: I know this is insane, but the universe gave it to me.
It creates a specific type of humor. It’s the humor of the subconscious.

But there’s a downside to the "this occurred to me in a dream" trend. It romanticizes the idea that we don't have to work for our ideas. McCartney didn't just "get" Yesterday; he had been playing music for over a decade. Mendeleev didn't just "get" the Periodic Table; he was an expert chemist. The dream is the finisher, not the foundation.
Why some dreams feel profound and others are trash
Ever had a dream that felt like the secret to the universe, only to wake up and realize it was just a pun about a sandwich? That's because the "feeling of insight" is a neurological trigger.
Your brain can trigger the "Aha!" feeling without actually having a good idea. This is why you need to vet your dream insights. Neuroscientist John Kounios, who co-authored The Eureka Factor, notes that while sleep facilitates insight, the "feeling" of truth in a dream is often just your amygdala firing off while your logic centers are napping.
How to Actually Use This (Actionable Insights)
If you want to capitalize on the this occurred to me in a dream phenomenon, you can’t just hope for it. You have to prime the pump.
- Incubation: Spend the last 20 minutes before bed looking at the problem you want to solve. Don't stress over it. Just look at it. This puts the "data" at the top of your brain's "to-process" list.
- The "Napping with a Key" Method: Salvador Dalí and Thomas Edison both used this. They would sit in a chair with a heavy object (like a key or a ball) in their hand. Just as they drifted off and their muscles relaxed, the object would drop, hitting the floor and waking them up. This caught them in the "hypnagogic state"—the border between wakefulness and sleep where creativity is highest.
- Voice Memos over Typing: If you wake up with a "this occurred to me in a dream" moment, don't turn on the lights or start typing on a bright phone screen. The blue light will jerk your brain into "alert mode" and erase the fragile memory trace. Use a voice recorder in the dark.
- Keep a "Bug Journal": Instead of a dream journal, keep a list of things you’re frustrated by. Your brain loves solving frustrations during REM.
The next time you see a post starting with this occurred to me in a dream, remember that it’s a tiny window into the most sophisticated biological computer on the planet doing its weirdest, most uninhibited work.
To make this work for you, start by keeping a notebook within arm's reach of your bed. Don't worry about grammar or making sense in the moment. Just capture the core images. Over time, you’ll start to see patterns in how your brain solves problems when you aren't looking. Stop trying to force the breakthrough during your 9-to-5 and start letting your subconscious do the night shift. It's much better at it than you are.
The goal isn't just to have a "cool dream." The goal is to build a bridge between your resting mind and your waking life so that the next time a brilliant solution occurs to you in a dream, you’re actually awake enough to catch it.
