While I understand the desire to use less vague terminology, to hallucinate usually implies that it is done involuntarily.
Based on your description of your abilities, have you considered that what you're describing is spatial thinking, rather than visual imagery? It is common for people with aphantasia to retain strong spatial cognition.
Point taken. Merriam-Webster says "usually arising from disorder of the nervous system or in response to drugs (such as LSD)" so I take "usually" to mean not always.
Regardless I hope the distinction I was drawing comes across clearly.
Regarding spacial thinking, yes it seems fairly accurate however where I would expect it to break down would be recollection of colors, touch, sounds, tastes, or smells. But I don't feel I experience such a breakdown in ability to recall those either albeit in the same conceptualized not-connected-to-my-realtime-senses way.
Out of the examples given in this thread I would say faces are the most challenging object to recall. Though, depending on the distinction of the features I can also do that without much difficulty.
> where I would expect it to break down would be recollection of colors...
Could that not be explained by simply storing that information as "textual" data? As in: using spatial imagery to recall the layout of a room, and basic knowledge to recall the color of the walls.
> ...touch, sounds, tastes, or smells.
These other senses are considered separate from the topic of Aphantasia. It seems there are many people with good visual imagery, but none of the other senses... as well as people with zero visual imagery, but some or all of the other senses.
I have zero across the board, unfortunately.
Could you explain your taste or smell imagery? My recollection only goes as far as "I remember liking this dish more than most things".
Perhaps I have overblown the ability to recall taste or smell, or at least it was incorrect to say there isn't some level of breakdown in comparison to the spatial/visual recollection we were discussing.
In general, I think of it in the terms you might hear someone on the food network describe a dish. "High notes", "low notes", "mellow", "pungent". On Sunday I made biscuits and sawmill gravy (good southern boy that I am). Sawmill gravy has a distinct profile, it's a base of nutty/earthy from the roux and peppery. I start describing the constituent parts, however if you asked me to describe "peppery" now it's getting more difficult. The only way I would have to describe it would be how your tongue and throat burns when you taste it.
You can see I'm getting more vague and conceptual.
It's entirely possible that as you say this is just "textual" data, however that feels like a drab description of what feels to me like a more vivid experience. It feels as if there "more to it" than just recalling information.
Unrelated, but I also think it's interesting how as we start talking about other senses how entangled memory is. We aren't talking about a nondescript sphere hallucination in my visual field anymore, but rather a memory of my Sunday brunch. When I imagine the smell of beer I inevitably will recall the last time I was at the bar with some mates and the spatial/visual memory of that space as well as my emotional state, etc.
