I’m on the “needs to sketch” side of things for the most part. I can construct an image in my mind, but this is basically mentally sketching. I am not able to think “apple”, close my eyes and see an image of an apple in my mind. I need to mentally sketch the shape, mentally add the colour, mentally add the blemishes and even then i can only hold a vague wavering image.
However, this is only true for me in a normal state of consciousness. Affected by some drugs, or asleep and dreaming, I don’t have to do this mental sketching. I’d never really considered it as such before, but I’ve just realized that this difference is one of the primary effects I associate with being in an altered state of consciousness; detailed images appear both deliberately or spontaneously. It’s one of my favorite aspects of both drug use and sleeping.
Anecdotal of course, but I thought interesting enough to add as I hadn’t seen it mentioned in the link or by anyone else that they can have both experiences at different times under different conditions.
FWIW I’m also terrible at remembering and recognizing faces, remembering the past, and navigating (the last not in the sense of being unable to use maps, but rather in the sense that I don’t easily end up with a mental map of a building that I am walking through or exploring which is new to me), which were all mentioned in the link.
