4% is a pretty big chunk of the population. That's 1 in every 25 people. Which makes it all the more insane that nobody realised it existed as a condition until just a few years ago.

I don't see things in my head, it's still blank but i can imagine the concepts. Do i have aphantasia? My dreams are vivid tho

I found it very interesting to learn that they believe aphantasics can form the mental image, they just can't access it. Minds are amazing!

Any mental imagery in general? Like through mind's eye? Dreaming? I had a mind palace (like no joke) it took me years to build into something I could use, and I had a few seizures in relatively quick succession and I cannot imagine images with nearly the same clarity. My dreams are like trying to swim in molasses while wearing scuffed scratched glasses, and I haven't been able to access my mind palace in years. Any time I close my eyes I just see vague blurry shapes and colors, there's an environment there but I can't see it. Now, I can still see faces and remember them, but imagining in my head kissing my girlfriend is impossible. Her face warps and melts and my mental vision goes fuzzy.
