I've been able to lucid dream on a few occasions. What I really want is the ability to vividly imagine constructions while awake. Like design an A/C motor in my head without paper. Not to that degree but those fuzzy concepts that you loosely feel the connections of, I'd like to be able to 'draw it out' in my mind and use those visuals to work out other aspects.

Yup, me too. Apparently the capability to form vivid mental images is not a human universal. See this informal poll: https://twitter.com/backus/status/1091203973246111744?lang=e.... Unfortunately, I fall into the 27% that choose (1), i.e. they see nothing.

I really, really, really wish vividness of mental images would be trainable. I so want it.

I find it hard to believe that 39% see a red star or that 57% see a pink or red star. After minutes of trying, I can vaguely fool myself into thinking I can see (2) a faint black on black outline of a star as if you traced it out the way you'd draw it with crossing lines--I was mentally tracing out that pattern repeatedly.

Color is rare. I mostly don't even notice in most dreams except a very few where it's central, like the one time I saw a colorful dreamcatcher-like crystal mobile-thing after waking from a dream and enjoying still having it from my dream, only to wake up and realize that they were both dreams. Doh!

I keep believing I can learn to visualize based on the fact that seeing is hallucinating. We take samples of light and imagine that we're actually seeing the world when really we're guessing that's what it is and synthesizing what we see. A great example of this was when I came back from a tropical vacation and back in the city a leaf blew past my feet. I swear I clearly saw a small lizard (like I'd testify that I saw a glimpse of one) as I had been seeing for the past few weeks. I saw the leaf on the second glance. So if I can conjure a lizard, I can draw some cylinders and wires eventually.

Most of the time I can't visualize either while awake but sometimes I can and my dreaming is almost always in color (I've had dreams where part of it turned grayscale and that was quite distinctive). I also over decades of sleep issues noticed that I often visualize unintentionally right before I fall asleep and sometimes attempting to do so can help me get to sleep. Some people seem to think that NMDA receptors might be involved somehow. I think in my case images do sometimes appear very briefly even when I can't visualize. On the flip side, I don't think even people who visualize well are usually able to hold a detailed image in mind for a long time and examine different parts of it individually (however I could be wrong about this, it is just my impression; I think people can usually recall the image at least a few times). It might be that my brain is just prioritizing a different representation.

My internal audio reproduction seems to be quite good (which would be great if I could remember more music, or at least whole songs, to play on my internal jukebox :/ - sometimes I do remember more when dreaming). I think recall/visualization/etc. is affected by limited working memory capacity and how working and long term memory interact; I suspect that is often the major limitation when awake also and would still apply to some extent when asleep (although things can clearly work somewhat differently when asleep).

I do believe that a majority of people can visualize fairly easily since it seems like most people can describe the appearance of someone they just met when not looking at them, which I am unable to do (most days). Yes there are non visual tricks to do that, but it does seem like many people do that type of thing effortlessly and also for things they are less likely to have previously learned tricks about. When I do know someone better I seem to be better able to recognize their distinctive style of movement than most people.

Dreaming is strange... lately I haven't been wanting to be aware of my dreams at all since I often end up with events looping while I am increasingly paralyzed (and of course everyone else want me to do something). I've noticed this seems more likely to happen on days I take baclofen (as a help stay asleep sleep aid), but it happens at other times also and happened occasionaly before I ever took baclofen.
