I don't see anyone claiming that they are "able to imagine an picture with [their] eyes open and have it cover the real world".
You specified "eyes open". Are you able to visualize things with your eyes closed?
Regardless, the way journalists talk about aphantasia, or more specifically, the opposite of aphantasia, has led a lot of people to believe this is possible (at least, I believed it based on what people have said they can do).
Maybe I am just exaggerating then, but i think this whole topic has got a lot of people worried that they are not normal. I don't think it's good for the mental health of hypochondriacs.
It's clear everyone is hardwired to see stuff like faces in something as simple as ":)", I feel it's related, but it's not my field, I can only wonder.
Is there any science done on this particular topic? It sure is super interesting but all I see about it is anecdote or very surface level stuff. It's clear some people do it better than others (my anecdata seems to indicate creative types might tap into it better?), but since most people is also affected by certain optical effects or tricks, the ability has to be present in everyone to a degree. Might be a thing that needs to be exploited consciously to make it "vivid".
It could also be a matter of priorities in perception. Like some people remembers lyrics better than songs, or numbers better than images. Maybe we are just taking our vision of the world in the way that's the most comfortable, and for some people it's images/sounds and for others "plaintext" information.
I know I really got a thing for visual information, as I can tell stuff like typos not from reading a word, but from noticing its shape is "off", like I'm remembering a printout of the word instead of the word character-by-character. (note that difference in typesetting does not affect the "shape" to throw me off. Unless it's very weird handwritten text, but that throws everyone off)
That would be like lucid dreaming while awake and I'd imagine it would be more well documented considering half of this thread claims to be able to do it. Actually, why are so many people trying to lucid dream at all if this level of visualisation is so common?
I don't think anyone is claiming that the latter is widespread, and I also don't think you're acknowledging that there are many people who can't do the former at all (myself included).
If you ask me to imagine something, there is no visual component to that at all for me. Internally, externally, nowhere.
Moving the goalposts is bad arguing. Bad arguing is often due to bad-faith arguing; but good arguing is hard, so it's also often accidental. Yet, people equate pointing out flaws in an argument with accusations of intellectual dishonesty: it's been politicised.

Sorry, but this is too funny. There's some sort of fundamental difficulty when humans are trying to compare their varying (or not?) qualia.
Like those stoner-philosphy questions. ("Is the 'red' I see the same hue as the 'red' you see? How would we ever know??")
There's an element of that unsolvable problem here; of knowing whether the other person is describing their internal mental state using the same definitions as you are.
Even if you can think of an object, even complex ones, and determine through a visual method its properties, shapes and colors, it's "nowhere" relative to real life visuals. You could be spinning in place or blind and you can still visualize the image. I could think of a scene with a very bright light but I'm really thinking of a white color or a gradient, it's obviously not going to blind me because it's now flowing through my optic nerves. I mean I can do something like divide a screen in two regions with an imaginary line, but it's not some sort of futuristic HUD.
That's kinda why I think there's some relation between our ability to mentally visualize an image and the ability to recognize a face or find shapes in stuff like Rorschach tests. In other words I think everyone has the ability to visualize images mentally, they just don't exploit it because maybe they put more weight on other details. Where I can remember and play with images and sounds mentally with no effort, other people can remember huge amounts of text, or do complex math instead. It might be a matter of specialization, perhaps?
