Hey! Congrats on the lucid

The really really vivid ones are still kinda hit or miss with me...I'll try to will things to appear and sometimes they do, sometimes they don't, or sometimes they appear but just look all wrong. I find that a slightly more passive approach is sometimes helpful. In otherwords, next time you're lucid, just go along with whatever story is already playing. Then maybe alter things around you slightly, rather than trying to compose an entire new story. It's more relaxing and allows you to focus better. Speaking of focus, something I like to do alot which is occasionally helpful, is to look at my hands when I'm lucid. If your'e near a mirror or can manifest one rather easily, a reflection of yourself can also help you focus.

Actually this is all excellent advice for myself as well.

Good luck!
