Here is some context: Early in the aphantasia discourse, someone asked a group I was in to do a mental exercise: Imagine an apple. Can you tell what color it is? What variety? Can you tell the lighting? Is it against a background? Does it have a texture? Imagine cutting into it. And so on. For me, not only was the color, variety, lighting, and texture crystal clear, but I noticed that when I mentally "cut into" the apple, I could see where the pigment from the broken skin cells had been smeared by the action of the knife into the fleshy white interior of the apple. This happened "by itself", I didn't have to try to make it happen. It was at a level of crisp detail that would be difficult to see with the naked eye without holding it very close. That was the first time I had paid attention to the exact level of detail that appears in my mental imagery, and it hadn't occurred to me before that it might be unusual. Based on what other people describe of their experience, it seems pretty clear to me that there is real variation in mental imagery, and people are not just "describing the same thing differently".

I can _remember_ the properties of an apple - approximate size, weight (my hand does not instantly drop to the floor due to its weight), etc. I can't _imagine_ an apple in my hand if you defined the colour, size or weight (for example, purple, 50cm diameter and 100Kg). In my mind I am recalling a _memory_ of holding an apple in my hand - not imagining the one according to your specifications. One example I can give is being tasked with rearranging desks in an office. I can't for the life of me _imagine_ what the desks would look like ahead of physically moving them into place. I can make an educated guess based on their length/width but certainly not "picture" how they would look arranged without physically moving them. It's like my brain BSODs when computing the image! The same applies to people - I can only recall a memory of someone - not imagine them sitting on a bench in front of me. I might remember a memory of the person on _a_ bench but certainly not the one in front of me.

  Can I ask you a personal question? How do you imagine sex? I thought that everyone kinda thought about themselves doing it with someone else, a bit like a porn movie that you make in your own mind. I can't imagine it being at all interesting to just think about it the way you are talking about it, like it would just be a sort of description of what the other person looks like, without the multifaceted sensations. Touch, smell, visuals. And if you can't imagine it, how do you go about ever doing anything about getting it? It's like saying you want a juicy burger without imagining yourself eating it. Like a paper description of an experience, rather than a simulation of it. It doesn't seem motivating enough that you'd bother washing yourself, getting nice clothes, and going to chat with women.

    I have so many questions to ask people with aphantasia related to sex, but it would get uncomfortably personal, so maybe best not to. The best I can do: do people with aphantasia only get aroused if the stimulus is present? Can't they not get horny just imagining things, like I imagine most people can? Does steamy literature do anything for them? I imagine it doesn't, since if you cannot imagine things then words on a page just have no power. In my opinion, the fact erotic literature exists is proof aphantasia is not normal. Words cannot be arousing if you cannot imagine things "in your mind's eye".

        Hmm, no? The words must elicit images and sensations, otherwise they wouldn't work as erotica. Words are just words. If you cannot picture what they are describing, you cannot get aroused.

    That'd be a tiny washing machine, to be fair. That said, a 50cm diameter apple would weigh maybe half that, unless it's made entirely of water ice.

but are those details fabricated on demand? I don't have any trouble following your path of increased detail, but if someone says "imagine an apple", I get a vaguely apple-shaped, generally redish object (I like cosmic crisp), which only becomes detailed if I "navigate my mental eye" closer.

  I think that is pretty normal while dreaming, daydreaming, or awake if you don't have aphantasia. Someone skilled in neural-linguistic programming can guide someone into developing greater and greater details. Psychedelics and certain meditative practices can enhance this effect. There are also specific practices that allow imagined object to take a life of its own. That's in the private imaginative mindspace. There are other mindspaces. There was one particular dream where I can tell, it was procedurally generated on-demand. When I deliberately took an unusual turn, the entire realm stuttered as whole new areas got procedurally generated. There were other spaces where it was not like that.

When you image slicing, does the video your head renders smooth or jittery string of pictures strung together?

  For me the default is typically an instant view of whatever is described, first an apple, then when I read "sliced" now it's suddenly in slices. But if I want to image motion I can easily do that also, like of a knife cutting down through an apple and the two halves falling to either side, just like a video but with a generic background and other simplifications, like the knife suddenly disappears when the cut is complete.
