Imagine being able to replay every detail of a moment—the exact shade of someone’s shirt, the precise words they spoke, or even the way the moonlight danced on a boat years after it happened. Sounds like a superpower, right? But here’s where it gets controversial: this isn’t just a fantasy—it’s a real cognitive phenomenon called hyperphantasia. And while it might sound like a dream, it’s not without its complexities.**
As a child, I struggled with insomnia. But at age 11, I discovered a peculiar remedy: mentally recreating the movie Mamma Mia! frame by frame. I’d replay the dialogue, visualize the characters’ outfits, and by the time they arrived flustered from their journey, I’d drift off to sleep. It wasn’t until years later that I learned not everyone could do this. My ability to conjure such vivid scenes—down to the exact blue of the sea or the inflection of a line—has a name: hyperphantasia. And this is the part most people miss: it’s not just about visuals; it can extend to sounds, textures, and even emotions.
Hyperphantasia is a cognitive trait characterized by an extraordinary ability to generate lifelike mental imagery. Coined just a decade ago, it’s still a developing area of science. Those with this trait can create detailed, multisensory scenarios in their minds—like designing a world with the precision of a 3D modeling software. But how do we measure this? The Vividness of Visual Imagery Questionnaire (VVIQ) is a popular tool, but researchers are now seeking more objective methods to study the brain’s imagery-generating processes. Here’s the kicker: what one person considers ‘vivid’ might be entirely different for someone else, leaving scientists with more questions than answers.
For me, hyperphantasia means I can recall the clothes someone wore the day we met or quote conversations word-for-word. It’s like having a mental archive at my fingertips. But it’s not all sunshine and rainbows. While I can’t remember dates or times with precision, I can vividly relive moments—both good and bad. But here’s where it gets even more intriguing: for the 1% of the population with aphantasia, the opposite is true. They experience no mental imagery, making phrases like ‘picture this’ purely metaphorical.
Aphantasia, the counterpart to hyperphantasia, can be multisensory, affecting not just visuals but also sounds, tastes, and touch. Joel Pearson, a cognitive neuroscience professor, explains that some people can’t imagine music, temperatures, or even textures. Conversely, hyperphantasia—which I and an estimated 5.9% of the population have—can amplify these senses, sometimes to an overwhelming degree. Take Alanna Carlson, a lawyer and executive coach, who describes her mind as a design tool, rotating objects in her brain to examine them from every angle. ‘I can keep my eyes open and still see it,’ she says, ‘but it’s not a hallucination.’
But here’s the controversial part: while hyperphantasia can be a gift, it’s also a double-edged sword. For Carlson, who has experienced PTSD, traumatic memories can be hauntingly vivid. Joel Pearson’s research supports this, showing that those with strong visual imagery have heightened emotional responses to frightening scenarios. So, while hyperphantasia can be a tool for creativity and memory, it can also make it harder to distance oneself from painful experiences.
The terms aphantasia and hyperphantasia were coined in 2015 by British neurologist Adam Zeman after a patient lost their ability to imagine following a cardiac procedure. Zeman’s fascination with the human mind’s capacity for imagination led him to explore how these traits fit into the larger puzzle of cognition and personality. ‘Imagination is what allows us to detach from the present, relive the past, and anticipate the future,’ he says. But here’s the question that sparks debate: if aphantasia doesn’t hinder thinking or memory, what does it truly mean for our understanding of the mind?
For Richard Arblaster, discovering his hyperphantasia was a revelation. After losing his best friend, he found comfort in imagining them walking through the woods together. Now, as a piano teacher, he sees his ability to visualize as a powerful teaching tool. ‘It’s like having a time machine,’ he says. ‘You can place anyone in any setting at any time.’
So, here’s the thought-provoking question for you: If imagination is such a fundamental part of the human experience, what does it mean for those who experience it differently? Is hyperphantasia a superpower, a burden, or simply another shade of the human mind? Let’s discuss in the comments—I’m curious to hear your thoughts!
