Thanks for sharing! I cannot relate with this sort of memory however many aphantasics can. It sounds like you are exercising spatial imagery and motor imagery (the mental simulation of physical movement).
Based on limited data, it appears that spatial imagery is often still accessible by people with visual aphantasia. Motor imagery is less commonly discussed or examined, but I suspect strong motor imagery may be a little less common in aphantasics.
And not only are there spectrums of vividness in different domains (visual, auditory, etc.) but also vast variability in things such as the imaginable content (ie. objects vs a places or faces) and sensory recall vs novel imaginings – my brother and dad, for instance, have eidetic memory but cannot manipulate the imagery or imagine anything they haven’t seen, exactly as they actually saw it with their eyes….
Sorry, I can get carried away 😅 can you imagine places you arent as familiar with? Also, can you imagine someone close to you walking through your imagined house?
