Not the same person, but have a similar condition, so I’ll take a go at it. Sample size of one here.

> Can you feel the cup?

No. There really isn’t a specific cup.

> Can you imagine holding it in your hands, caressing the rim, scooping the inside, and feeling the pressure on your hands?

Yes, I can imagine these actions, but it’s more about remembering what it might be like to feel that sensation again and is somewhat disconnected from the cup. I end up wanting to remember a different, real cup, when I might have done those actions. Like how I can remember when I last cut off circulation in my hands carrying a heavy plastic bag, say. I know how that feels, but it’s not something I’m particularly good at imagining visually - with a mental image.

> Can you imagine your hands getting wet or even the pain of a thousand shards of glass as the cup suddenly shatters?

Not quite, and no, I can’t really imagine the shattering. I mean, I can remember a time when a cup fell and shattered and sort of associate that, but just “visualizing” the pain or shattering seems impossible. I can play concept association and “imagine” the cup exploding outwards like a grenade, but it’s not visual or concrete, it’s more conceptual and I lose any connection to pain or feeling or hands and fingers. The more I try to make up without associating with a memory, the more abstract (verbal, less real) the “imagining” seems.

> Does it make a sound?

I can imagine sounds, and get songs stuck in my head, so I have some idea of how mental visualization should work for me, but it doesn’t visually work that way. It’s interesting that to me, just now, imagining the sound of a cup shattering produces an associated concept mentally than the reverse … I can’t easily go from a shattered or falling cup concept to the sound, but I can relatively easily do the reverse: I can go almost instantly from imagining the sound of a shattered cup to thinking of a shattered or falling cup and what that might look like or how the shards might feel.

> Can you smell the tea?

Again, thinking of smells first brings back sounds and memories more strongly than visuals would for me, and when I was trying to think of an image, it was abstract - there were no sounds or smells in particular and it wasn’t something I could interact with. More of a model of a cup. Even thinking of the interactions or how something would feel, I now realize, is thinking about feelings and memories of feelings - that visualizing my other senses such as touch, smell or hearing is much easier for me than to visualize based on appearances.

> Can you taste it?

Not from the mental imagining of the cup, no. If I remember the sounds of when I was at a tea house, or if I pull up a photo of a cup of tea on my phone, then I can imagine the taste. But it feels disconnected to try and purely jump from a “visual” cup to thinking, it tastes like tea. Thinking of how certain foods taste does bring up memories and can make my mouth water imagining or remembering how certain foods tasted, though. Thinking of a taste can bring back the smells, the feeling of heat rising off a dish or hot plate, the sounds of sizzling, and a memory of what it would look like. But there still isn’t really a “picture” and if I wasn’t looking at a photo on my phone, all I could tell you about my visual imaginings would be words or concepts. I can tell that something is missing in my imagining because of how different it is to go from non-visual senses to other non-visual senses. But visuals … don’t have the same mental impact unless I can see them in front of me, e.g. on a computer screen. For others, remembering a layout might trigger memories of details, for me it is the opposite - I remember the layout of a flowchart by remembering which details are connected and then from there I can describe the diagram’s layout in my head.

But again, sample size of one here.
