Oh, my goodness. This is gold! 
Out of the many guides to lucid dreaming I’ve read here, I’ve never seen one that stresses the importance of vividness as much as yours. And the whole time I was reading your guide, I kept having those “realization” moments, when I thought, “Of course, that makes sense! Why didn’t I think of that?” I loved reading it, and hopefully you’ll continue to update it whenever possible!
Another reason why I had those realization moments was because I understood exactly what you were trying to say. I myself never have vivid dreams unless they’re induced by techniques, but those weren’t my normal, everyday dreams. In fact, I made a post a while ago addressing that problem, see here if you want: [Vivid vs. Hazy Dreams)
So basically when I read your guide I thought, “I have to do this.” Thank you so much for the wonderful explanations!
