Just a quick question, How vivid are Lucid Dreams?

Are they as if you're re-living a memory in your head? (So kind of faded and distant)

or are they like waking reality? Like as if you're not really sleeping at all, and you're just awake in some crazy world?


This question has plagued my mind for a while now, And I just wanted to know how vivid lucid dreams are for you.
