Tks!

I stay with the 5 levels of lucidity. It could be endless levels, but to control and compare with others oneironauts 5 is ok to me. I liked the definition of Marc Breault posted above and maybe I can work with it and refine it to my dream states.

And this is what I like about standards. When I talk to someone I can say I was in level 4 of lucidity and he/she knows right away exactly what I'm talking about, because he/she already got to this level of lucidity and knows exactly how it feels.

But the first level (non-lucid) is no-lucid at all, so Marc suggests 4 levels. I prefer 5 levels, with the first one being the pre-lucid state.
