I'm not sure what to say. When I try to visualize an apple or hammer or tractor I see a vague representation of the object for a very brief time (I have to do a constant refresh if I want to keep seeing it). I can put a worm half way in the apple or change its color but again, nothing stays for more than a split second and no minute details. It's hard to explain but kind of like I don't really see the object but just an idea of the object, which is the reality isn't it?
Thank you for sharing. Sounds like you may have hypophantasia, i.e. a lower than normal ability to visualise.
Normal visualisers see more or less an accurate visual representation of the object they imagine, rather than "the idea of an object". Those with vivid visualisation (hyperphants) can often see it just as clearly as they see with their physical eyes, for however long they please.
Visualisation can be hard to grasp if you have always had aphantasia - it's a bit like being born blind and trying to imagine seeing: you have no frame of reference.
It is very obvious to those who lose their ability to visualise after eg. brain damage.
This is one example of that, although it may be experienced differently by different people.
What I can say is that normal visualisers and hyperphants would not say they see "the idea of the object" since they actually see a visual representation of the thing in their mind's eye. They simply see the object visually in their minds. Possibly not entirely life-like but not entirely unlike either, depending on where exactly they are on the visualisation scale.
I myself seem to compensate with a relatively acute spatial sense. I do not see anything in my mind's eye, but I have a "mental sonar" which I can use to manipulate objects in my mind without seeing them - much like I imagine someone born blind would. I can map out my surroundings mentally and rotate objects in my mind, although this is not accompanied by the usual visual representation of those objects.
