I'm interested in practicing LD's and eventually perfecting them- but there's a few questions that's still in my head that I can't seem to find the answer to, one of them being the transition into a dream.

When doing any kind of technique to induce a lucid dream, do you just "appear" in the dream? How do you know and what does it feel like when you've finally slipped into the dream world? How do you "see" theoretically lol. And I've read that lucid dreams and REM dreams are usually so vivid and so real that it comes very close to resemble reality- hence the reality checks. Does this mean that when you're in a lucid dream that everything around you is in color and that you all your 5 senses work? I'm not sure if I worded that question right. In other words, on a scale of 1-10, 10 being 99% like reality, how real is a lucid dream?
