Hello The idea: creating a meditative/fantasy "training place" for lucid skills. Like a "practice" lucid dream, only it is not a dream. It is a meditative state.
Some days ago, I started meditating. I don't know if meditating would be the right word, but I closed my eyes and imagined I was walking around in some fantasy world.
In this world, I did different things I would like to try in lucid dreams. Like mind control and shape shifting..
The day after I started doing this 'meditating' I had a dream where I shape shifted from human to wolf.
Then, some days after, I had a lucid dream (DILD) where I had to use mind control. And from the practicing in the fantasy world, I knew exactly how to do it. It was easy as nothing.
So when the lucid dream comes, you will 'know' the feeling of it, and how you do it, from the practice dojo.
For example: People wanting to grow wings and fly, can close their eyes and imagining growing wings. How if feels when they grow themselves out of the body, they weight of them and the wind in rustling feathers. Then they can imagine they are running off a cliff, flapping their wings. Getting higher and higher.

This will give people confidence in the lucid dream, since they know how it's done. In a world you imagine, you decide everything. So unless you decide to fail, you can't fail.

Summary: Imagining yourself doing things in a fantasy world will make it easier to do in a lucid dream.

Perhaps this is an old idea, but I haven't seen it here before.
