I've trained myself to have powers in the dream, but I rarely, fully know that it's a dream, so it doesn't really help when it's all psychological.

Can I just say that I agree with the other poster. I used to have a lot of nightmares. I didn't do it purposely, but I did figure out that lucid dreaming was the way to solve that issue.

I got interested in lucid dreaming for its own sake, and trained myself for it. I did all the common stuff in the guides, and eventually I had a habit of many times a day rubbing the back of my hand or something else tactile and asking myself if I was dreaming. After quite some time it did start to actually work in my dreams. I would frequently become "aware" in my dream and realise I was dreaming, and in my dream I would dream I would have control, but once I woke up it didn't even really feel like I had full control. It was not the experience I had been expecting, where everything becomes clearer, you can literally consciously control the dream. It was more like dreaming that I knew I was dreaming, and then controlling the dream, but I could never quite control it to the full extent I wanted to. No matter how much I practiced, this is all I achieved.

However, it wasn't nothing. It did let me start to realise I was dreaming in nightmares, and immediately just change them and become "in control" to the point where I could push back on whatever the nightmare was about, dictate on my terms. It still wasn't full lucid/awake control, but it was enough that I become the power in the dream, not the subject of the nightmare.

I really encourage you to keep trying. It took a lot of repetition during the day for the habit to finally enter my dreams. A lot more than I expected. But it did eventually work, to the extent I mentioned.

You can train for that. There are enough guides on the internet how to do it
