Iriba, I too rarely have lucid moments, despite having actively been into lucid dreaming for plenty of years now, so I can imagine how you might feel. At the worst of times I find it quite frustrating, though most of the time it's just an annoyance, as I often think about how I still have plenty of time, in principle, to have more lucid experiences.

Because of my health, my experience on vividness and detail (especially while lucid) seems to be that it relates a lot to that aspect of "health". When I've been at my best in terms of health is also when I've had my most vivid dreams and is also when I am typically more likely to actually become lucid.

Perhaps this is not a usual relationship between things for most people. From my experience alone, I would encourage you to find out if there's something that is impacting your sleep, mood patterns or physical/mental health in a significant way and think about whether you can improve this or not.

My personal opinion only, I think sometimes creating improvement in a specific part of our lives is not about direct intervention in that area in itself. So it could be the case that affecting something in a less direct way can create improvements too.
