I am also aphantastic, and I don't even get to dream properly. I had a dream perhaps no more than 10 times throughout my life, and almost always due to some unusual circumstances (very rough hangover, grief, broken heart). Even experiences with rather high doses of psilocybin or LSD were profoundly non-visual for me, and I made several attempts to get there.
How’s your sleep quality? I (aphantasic) only ever dream on weekends when I sleep in over 8 hours (rare), and having to get up to pee after 4 hours also cuts in.
Interesting that you say you had no visuals from LSD. How high a dose?
It's surprising to me, because as far as I understand it, psychedelic visuals aren't really akin to daydreams or internally generated imagery, but abnormal processing of external imagery. At least for relatively mild experiences. Something like a DMT breakthrough is a whole other story from what I hear, though I've never been there myself.
