You’re sitting in a quiet room, and for a split second, you feel your phone vibrate in your pocket. You reach down. Nothing. The screen is dark, there are no notifications, and honestly, the phone wasn't even in that pocket to begin with. Your brain was just playing tricks on me—and by "me," I mean that internal sense of self we all rely on to navigate the world. It’s called Phantom Vibration Syndrome, and it is just the tip of the iceberg when it comes to how our gray matter lies to us daily.
The truth is, our perception isn't a live video feed. It’s a messy, predictive simulation.
The Science of Why Perception Is a Lie
Most of us think our eyes and ears work like cameras and microphones. We assume they record the world and send the data to the brain for processing. Science says otherwise. Dr. Anil Seth, a professor of Cognitive and Computational Neuroscience at the University of Sussex, describes the brain as a "prediction engine." Instead of waiting for sensory input, your brain is constantly guessing what it’s about to see or hear based on past experiences.
When the guess is wrong, we call it an illusion. When the guess is right, we just call it "reality."
Take the "Hollow Mask Illusion," for example. If you look at the back of a plastic mask—the concave side—your brain will almost certainly "pop" it out so it looks like a normal, protruding face. You know it's hollow. You can see the edges. But your brain has spent a lifetime seeing faces as convex objects, so it overrides the actual light hitting your retinas. It’s playing tricks on me by forcing a familiar pattern onto an unfamiliar shape.

This isn't just a fun party trick. It’s a fundamental survival mechanism. In the wild, it’s better to mistake a rustling bush for a predator than to mistake a predator for a rustling bush. We are the descendants of the most paranoid primates.
When the Mind Plays Tricks on Me in the Dark
Have you ever seen a "ghost" in the corner of your eye while walking through a dim hallway? That’s pareidolia. It’s the same phenomenon that makes people see the face of Jesus on a piece of burnt toast or a man in the moon.
The human brain has a specialized area called the Fusiform Face Area (FFA). Its entire job is to detect faces. It is so hyper-active that it triggers at the slightest hint of two dots and a line. In low-light conditions, your brain lacks enough data to be certain about what’s in the shadows. To stay safe, it fills in the blanks with the most "important" thing it can think of: another human or a predator.
- Sensory Deprivation: If you’ve ever spent time in a completely silent, dark room, you might start hearing whispers or seeing geometric shapes. Without external input, the brain "turns up the gain" on internal noise.
- The Ganzfeld Effect: This involves staring at a uniform field of color (like half a ping-pong ball over your eyes) while listening to white noise. Within minutes, the brain gets bored and starts inventing complex hallucinations just to stay occupied.
It’s kinda wild to think that our "sober" reality is just a controlled hallucination that happens to coincide with the physical world.

The False Memory Trap
The tricks don't stop at what we see right now; they extend to everything we think we know about our past. Elizabeth Loftus, a world-renowned psychologist at the University of California, Irvine, has spent decades proving how easy it is to plant false memories.
In her famous "Lost in the Mall" study, researchers managed to convince about 25% of participants that they had been lost in a shopping mall as a child, even though it never happened. By simply having a trusted relative mention the event alongside real memories, the participants' brains integrated the fiction. They didn't just believe it; they "remembered" details like the color of the shirt the old man who found them was wearing.
Memories aren't files in a cabinet. They are reconstructed every time we think of them. Each time you pull a memory to the surface, you rewrite it slightly, often adding current emotions or new information into the old story. Your mind is playing tricks on me by making me believe my history is set in stone when it’s actually more like a Wikipedia page that anyone can edit.
Why We Fall for the Same Tricks Twice

Optical illusions work even when you know how they work. Look at the Adelson’s Checker-shadow illusion. Even if you measure the light intensity and prove that Square A and Square B are the exact same shade of gray, you literally cannot force your brain to see them as the same. The "trick" is hardwired into the neural circuitry that handles local contrast.
Then there’s the "McGurk Effect." If you see a video of someone’s mouth moving to say the sound "ga-ga" but the audio plays the sound "ba-ba," your brain will often report hearing "da-da." Your visual system overrides your auditory system because, in the brain’s hierarchy, seeing is believing. Even speech pathologists and neuroscientists who study this for a living fall for it every single time.
Practical Steps to Outsmart Your Own Brain
You can't stop your brain from playing tricks on me, but you can change how you react to them. Awareness is the first step toward intellectual humility.
- Verify your "vibrations." If you suffer from phantom phone vibrations, try moving your phone to a different pocket or leaving it on a table for an hour. This helps reset the neural pathways that are over-sensitized to tactile stimuli.
- Question your "first glance." When you see something weird in the dark or interpret a text message as being aggressive, pause. Ask yourself: "What is the most boring explanation for this?" Usually, the boring explanation is the right one.
- Record important events immediately. Since memory is so malleable, don't trust your "recollection" of a conversation or event three days later. If it’s important for work or personal life, write it down immediately.
- Practice mindfulness of the senses. Spend five minutes a day just noticing what you actually see—colors, shapes, light—without labeling them. This can help you distinguish between raw sensory data and the labels your brain tries to slap onto them.
Our brains are essentially biological supercomputers running outdated software designed for the Pleistocene era. They aren't trying to be malicious; they’re just trying to keep us alive in a world that is way more complex than we can actually perceive. Accept the glitches. They’re part of the human experience.
Final Takeaway
Next time you think the world is acting strange, remember that the most likely culprit is the three-pound lump of jelly sitting between your ears. It is a master of deception, a champion of shortcuts, and a relentless storyteller. Understanding these mental "tricks" doesn't make the world less magical; it actually makes the sheer complexity of human consciousness even more impressive. You aren't just an observer of reality; you are its creator.
Next steps for you:
- Test the McGurk Effect on YouTube to see the visual-auditory override in action for yourself.
- Check your "digital hygiene" by turning off haptic feedback on your phone for 48 hours to reduce phantom vibration triggers.
- Journal a "fixed" memory by asking a sibling or parent about a shared event and noting where your versions of the "truth" diverge.
