>>14229609damn me too. It's hard to explain. While my eyes are open, I can sort of roll my focus upward which takes me out of my actual field of view and allows me to daydream. If I shut my eyes, it's like shutting that path, too. Maybe the strain of keeping my eyes closed is distracting, I don't know.
In regards to the OP, ever since I was introduced to this 'aphantasia' meme (and it is a meme, in terms of its spread and normie self-diagnoses), I've had serious doubts. For one thing, how are two different people even supposed to compare their imaginations. It's like asking someone 'how do you think?'
If they even have an answer, you'll notice that any one person's answer will be totally different from another because everyone has different foundations from which they build self-understanding.
This aphantasia thing has been packaged in a way to set up gullible people on the net with an idealized and dumbed down form of imagination, that is, literally painting a canvas in your "mind's eye". And when a person finds that they don't mimic the presented skill of perfectly rendering a stable picture with focus-able details, they figure they're aphantasic despite never in their life having actually been inconvenienced by how their imagination works.
