I have read the stickies..

I just had 5 lucid dreams over the course of 3 days. I had full control which was cool. I need help changing the scene though.



I would close my eyes and know when I wake up It will be different. It only sort of works and it's not very vivid.


I would walk through a door and tell myself that the scene will be different. It only sort of works and I lose that scene.


When I tried these everything went black so I tried to make a scene of green hills and focused on them and it just sort of faded and my old dream came back and I lost Lucidity.
Is there a way that can make it more vivid and permanent?
