    see the thing is I can’t even tell if I can do this or not

    like I can think of something and know the shape and quality of it, but I don’t see it in my mind

    I’m a mechanical designer, I design tooling and machines all day, and my hobbies include woodworking and 3D printing functional stuff. right now I’m thinking of the design of a kumiko lamp, and the grid pattern I want to use, but I just don’t see it. it’s the same with the essentially lego tooling I design at work, I know this block has this shape and connects to this other one with this surface, and the assembly of 10 parts looks like whatever, but I do not see that shape when I think about it. it’s more that I know the description of it

    I can lucid dream, though, so that’s pretty sweet

      I used to have the same question. What finally convinced me was imagining an apple sitting on a table. When I try to imagine specific parts (e.g. the stem, or the specular shine on its skin, or water beads on its side) I can actually see that part of the apple in my head, and the images change when I change the color, form etc.

        why did that convince you? if i imagine an apple on a table i am unable to tell i “see” it or if i “know” it based on all the properties i know it should have. like, is it a mental image or a description mapped into some sort of imagined space?

          For me it’s a mental image, which is definitely distinct from a collection of descriptions. I don’t really know how to describe it, but it feels like my head uses circuitry close to other visual circuitry while I’m focusing on this kind of mental image. Almost like the mental image is “injected” into hardware/software used for other visual processing.

        yeah I’ve tried the apple thing a few times a year for the past few years, and not once have I felt like I was seeing it. I just think of the outline of an apple, maybe how the light would reflect off it, and of a colour. all separate
