This is interesting and I wonder if it might explain some apparent cases of aphantasia. Also seems relevant to some aphantasics experiencing mental imagery when using psychedelics.

I've never experienced visualization under the effect of hallucinogens, but I have once when I took very strong opiates.
When I took psychedelics they were still in effect when I went to sleep and I experienced unusually vivid and strange mental imagery. They call it closed-eye hallucinations, as opposed to mis-seeing the world around you while your eyes are open, which I also experienced.
