I have an iq of 158 or something like that I don’t care enough to remember it. I found out I had aphantasia a few years back from some video. I’m smart enough to get by in life. School is bad, things are hard. They aren’t in a way I like, but I deal with it. Aphantasia is limiting to say the least. Sure I can do anything anyone else can, but it’s hard for me to remember details of people, I can’t picture memories I have, it’s not fun. I just buy things at almost every gift shop I go to just to replace the memory I can’t picture. I know what it looks like, I just can’t imagine it. My memories are fuzzy, I take pictures all the time. I just want to be a baker. Fantasy is different for everyone. “Geniuses” can flourish under people who aren’t geniuses, but only because the people who teach them try to understand how to teach them. If they don’t try to understand, it doesn’t work. I’ve flourished under quite a few teachers, while I’ve sheltered myself under other ones. It’s all perspective and experience that shapes viewpoints. Fantasy to me, is being able to be free and imagine anything I want to imagine. I want to be free from the burdens of being compared to others, just because they do things the way they are told. I want to create, I want to enjoy, I want to LIVE. Aphantasia hasn’t stopped that, it hasn’t stopped my dreams, it taught me to grow around obstacles. Fantasy isn’t just creative, it’s a way of life. Aphantasia is part of fantasy just as much as it isn’t, you have to accept both in life to get anywhere. That is my answer to your question. It’s viewpoint, perspective, and many other things that make fantasy, not just creativity.
