Right, I misunderstood what you'd meant about control then. I think for most people that aren't naturals at dreaming lucidly, it's almost a given that the interest in lucid dreaming also involves wanting to be able to influence when you actually have lucidity.

I would say that if it's been a while since you've read those works, that you could actually go back and read them again a bit before you get into something new too; for one thing, it might be more convenient for you and besides that, reading about dreaming and lucidity on its own can be good at keeping your mind actively interested in the subject and therefore also more "vigilant" about a dreaming state too.
