Close your eyes. Right now. Try to picture a bright, juicy red apple sitting on a wooden table. Can you see the light reflecting off the skin? Is the stem slightly crooked? For most of you, a grainy or maybe even vivid 3D image just popped into your skull. But for about 2% to 4% of the population, there is absolutely nothing. Just darkness. They have a mind's eye that is essentially "blind," a condition we now call aphantasia.
It’s wild to think about.
For decades, we just assumed everyone was speaking metaphorically when they talked about "counting sheep" to fall asleep. It turns out, some people were actually seeing the sheep jump over the fence, while others were just thinking about the concept of sheep. This isn't just a quirky brain fact; it fundamentally changes how we process memories, navigate cities, and even grieve.
The Spectrum of Internal Imagery
The mind's eye isn't an "on or off" switch. It’s a sliding scale. On one end, you have hyperphantasia. These people see mental images so crisp they can barely distinguish them from reality. In the middle is where most of us live—kinda blurry, somewhat stable images that get the job done. Then you hit the low-visualizers and, finally, the aphantasics.
Adam Zeman, a professor of cognitive and behavioral neurology at the University of Exeter, coined the term aphantasia in 2015. He didn't discover it—the phenomenon was actually noted by Francis Galton way back in 1880—but Zeman gave it a name that stuck. He started investigating after a patient, known in the literature as MX, lost his ability to visualize after a minor surgical procedure.
Think about that for a second. Imagine waking up and your internal projector is just... unplugged.
What’s Actually Happening in the Brain?
Neurologically, the mind's eye is a complex dance between the frontal cortex (where we plan and ideate) and the visual cortex at the back of the brain. When you look at a real-life apple, signals go from your eyes to the visual cortex. When you imagine an apple, the frontal cortex sends a signal "backward" to the visual cortex to recreate that activity.
In people with a functioning mind's eye, the visual cortex lights up during imagination. In aphantasics? Not so much.
Research using fMRI scans suggests that the connection between these brain regions is just... different. It's not a "broken" brain. It's just a different wiring setup. A study published in Scientific Reports showed that people with aphantasia even show different physiological responses. Usually, if you imagine a bright light, your pupils will actually constrict. People without a mind's eye don't show that pupil contraction. Their bodies literally don't react to the "light" because the visual system isn't being triggered.
Living Without the Inner Movie
You might think life without a mind's eye would be a massive handicap. Honestly, it's usually not. Most people don't even realize they have it until they’re in their 20s or 30s and stumble across an article like this one.
Take Ed Catmull, the co-founder of Pixar and former president of Walt Disney Animation Studios. The guy literally helped build the most visual company on earth, and he has aphantasia. He can't see a single thing in his head. He navigates his world through spatial awareness and conceptual logic rather than "seeing" a map.
It impacts memory, too. This is often called Severely Deficient Autobiographical Memory (SDAM). If you can't re-visualize your wedding day or your high school graduation, those memories tend to feel more like a list of facts than a re-living of the experience. You know it happened. You remember who was there. But you aren't "there" again.
There's a flip side, though.
Aphantasics might actually be more resilient to certain types of trauma. PTSD is often driven by intrusive, vivid flashbacks—mental movies of the event that play on loop. If your mind's eye doesn't work, those visual "flashbacks" don't happen in the same way. You might still have the emotional or physical response, but the "horror movie" aspect is absent.
The Creativity Myth
There is this huge misconception that you need a mind's eye to be creative.
That is total nonsense.
In fact, some evidence suggests that aphantasics gravitate toward highly technical or even highly creative fields because they have to find workarounds. If you can't visualize a character, you describe them through their actions, their dialogue, or their "vibe." You build the world through logic and relationships rather than painting a mental picture.
Artists with aphantasia often use a lot of reference photos. They have to get the ideas out of their head and onto the paper or screen before they can "see" if it works. It’s an iterative process. It’s "doing" instead of just "dreaming."
Is There a Cure?
People always ask if they can "train" their mind's eye.

There are "image streaming" exercises and various "hacks" touted online, but the science is pretty thin. For the most part, you’re born with the visualization hardware you’ve got. While neuroplasticity is a real thing, you probably aren't going to go from total darkness to 4K Dolby Vision just by staring at a candle for ten minutes a day.
And that's okay.
Aphantasia isn't a disorder. It’s a variation. Just like some people are colorblind or some people have a better sense of smell. It’s just another way the human brain organizes reality.
Identifying Your Own Mental Imagery
If you’re curious where you fall, the standard tool used by researchers is the VVIQ—the Vividness of Visual Imagery Questionnaire. It asks you to rate how clearly you can see certain scenarios on a scale from "perfectly clear" to "no image at all."
- Visualize a rising sun. Can you see the colors? The clouds?
- Think of a friend’s face. Can you see the shape of their eyes?
- Imagine a shop you visit often. Can you see the layout of the shelves?
If your answer to all of these is "I just know what they look like, but I don't see them," welcome to the aphantasia club. It’s a pretty interesting place to be. You’re forced to rely on pure conceptual thought, which can make you an incredible problem solver.
Practical Steps for Navigating Your Mind
If you’ve realized your mind's eye is a bit dim, or totally dark, here is how to lean into it:
- Externalize your thinking. Since you can't "see" the plan in your head, use whiteboards, mind maps, and sketches. Don't try to hold a complex design in your skull; get it onto a screen or paper immediately.
- Use descriptive cues for memory. If you want to remember a vacation, don't just rely on your brain. Take more photos than the average person. Write down how things smelled or the specific words someone said. These "anchors" will help you reconstruct the memory later.
- Audit your learning style. If you’re a student, stop trying to "visualize the diagram" if that doesn't work for you. Convert that visual info into a narrative or a logical sequence of steps.
- Leverage spatial awareness. Many aphantasics are great at "knowing" where things are in space even if they can't "see" them. Trust that gut feeling of where the car is parked or how the furniture should fit in a room.
- Check for SDAM. If you struggle to remember your past, start a "memory journal." Just a few sentences a day can act as a hard drive for your life, ensuring those "fact-based" memories don't fade away entirely over time.
The mind's eye is one of the last great frontiers of cognitive science. We’re finally realizing that the person sitting next to us might be experiencing a completely different internal reality. Whether your head is a cinema or a quiet dark room, the end result—how you interact with the world—is what actually matters.
