There is a section titled "What's It Like To Visualize?" that provides instructions for creating a temporary after-image, then claims:

> This afterimage illusion, while a product of perception, serves as a bridge to understanding visualization. For those with aphantasia, it's a rare opportunity to "see" what visualization might be like for some visualizers.

Is that really what it is like for those of you who can visualize?

On the one hand it's much more realistic and detailed than an after-image; if I picture a red apple, and someone asks what kind of apple it was, I can retroactively say "oh, like a Red Delicious, really dark and shiny and with that concave part, not at all like a Macintosh or whatever. But it was a bit rounder than a normal Red Delicious probably because I was averaging towards a kind of typical 'red apple'."

(FWIW I think I'm near the upper end of detailed visualizing.)

But on the other hand it isn't located in my visual field, it's kind of in its own separate visual field. It doesn't have a spatial relationship to the objects in front of me and doesn't occlude them (although when I'm visualizing something carefully I lose a lot of my awareness of what I'm actually looking at because I'm not attending to it, even if my eyes are wide open).

If I am to believe that I am a visualizer. No, not really. With the negative "after image" it's almost like an artifact in your physical vision. More like seeing a floater IMO. But with the "mind's eye" it's completely non-physical. I can imagine an apple like I would see it with my eyes just strictly in my brain, but I can't "see" it. There is no visual output. It's very bizarre to put into words. I think of it like AR/VR. I can overlay objects onto my physical world.. AR. But I can also just think and manipulate things in some imaginary brain space... VR

I don't know how other people experience it, but it's not like a full-blown hallucination as the exercise would imply. Personally I experience it as something in between the concept of an object and the perception of an instance of one.

If someone says they're looking for a purse I would still have some ambiguity, visually represented, about the material, color, texture, shape and size, type of clasp, if it has a strap or a chain attached to it, if it was new or showed wear, if it appeared to be ful or empty and flat...

No, it is nothing like retinal fatigue, which is what they are referencing in that sentence.

The later section on "What Do Most Visualizers See?" is a better description, although the level of detail is highly dependent on effort, and lack of distraction.

And I'd argue that detail is not particularly important as the visualization is just there to represent conceptual things.

Sort of. For me it’s more like seeing out of a third eye (while also seeing out of your real eyes). Like how if you put your finger right in front of your face, you can see two images of it at once. With concentration I can ignore what my real eyes are seeing to prioritize the visualization, but the real eyes are constantly pulling my concentration back.

Not for me. My memories, fantasies, thoughts just look like movies. If I get deep into thought it takes over my whole perception and I don't see the world around me at all. Kind of scary when I get home from work and realize I was lost in thought and can't remember the drive.
