In case you missed my other comment linking to similar polls and stuff on Reddit: https://news.ycombinator.com/item?id=49469522. The hyperphantasia subreddit covers all other sense imagery too, and I am high on all of them.

Also, to be clear, my images usually are NOT spatially located, but I can choose to make them so if needed, and occasionally they just are spontaneously.

You might also find the work of Louis Sass ("Madness and Modernism", and other works) to be relevant, as he notes it is extremely common for schizophrenics to always be localizing (sensing) their thoughts have specific locations in space, or e.g. are "moving from the front of my head to the back", and other such extreme (and arguably unhelpful) spatialization of aspects of the mind's eye. He argues this might be part of why they are prone to hallucinations and delusion.
