Okay, I know other people have asked this before, but is it possible to have dream layers, like in inception? I know there is a lot of details in inception that are not at all like real lucid dream. What I want to know, is if there is a way to actually have a lucid dream in another lucid dream. I've had regular dreams like this, but not lucid ones. And, if it is possible, would it increase the length of your dreams.
