So I read this tutorial. LINK
This one thing in particular got me thinking. He wrote, "The only prerequisite is to know that dream feeling. That hazy feeling when you’re dreaming. Even when the dreams are vivid, the feeling is still there."

I was thinking about what the distinct difference between how a dream feels and how being awake feels. The feeling that is present in non-lucid, lucid, and even very clear and realistic dreams.

I want to know because I'm working on a technique which involves knowing that feeling, so if someone could give me a good description I would be grateful.

Thanks,
