I'm not quite sure if I have it or not. I visualize mostly in 3d but without a specific viewpoint, or more exactly I get a feel from how it would look from various viewpoints simultaneously. I find it easier to mentally see as a 2d picture, something I saw in photo, or on a screen. If I specifically force myself to imagine how it would look if I was at a specific position looking in a specific direction (i.e. do the 2d projection), I can in-paint in my mind starting from a black canvas, focusing sequentially my attention on a part of the canvas making details appear at the center of attention. I scan the canvas a few times in-painting details, and then I try to mentally take a step back visualize all those various details in a unique coherent picture, by un-focusing attention. It kinda work, but it needs to get into it. It's easier to imagine looking at a photo from the scene I'm trying to visualize.
I noticed my eyes do some REM when I do this. Color and illumination comes last. Closing eyes helps.
I can mentally do a "street-view" experience of my home, moving inside and answer question about details, but I need to focus my attention first on the relevant area. Those mental exercises are quite funny, not sure how useful they are though. Once you add some moving objects (like pendulums) in the scene in your mind, it gets even harder to make something coherent. Then you can add animals and people, wind. Noises, music. I guess when you add complexity, you must relax your attention to make a coherent global picture, then you get into a flow-like state, and it becomes more similar to a lucid dream. On the other hand of the spectrum, I'm not quite sure about auras too. It's kind like of synesthesia but for people instead of numbers. I guess the brain hallucinate colors around object/people to make it faster to process. I find it quite unnecessary to hallucinate rather than having a specific feel about the person. And I feel it's quite reductive/intolerant to put/interact with people into a category based on subconscious perception. But I guess that if I was a bouncer, I'll probably be seeing colors around people too. To conclude this already too long post, I think aphantasia is probably very correlated with hyper-attention. |
