Yeah, there's alot of this in the dream control tutorials. Passive control is one thing for example. You know something works the way it does in real life and you tweak it or use it to your advantage. Using rocket boots for flying or a wand for spells.

The more you visualize yourself doing any kind of dream control, with confidence, the easier it gets to do it once you're in the LD. As soon as you've done it once in a LD, you know it's possible and next time it will come alot easier. I had trouble using telekinesis until one day I did it, and now I can do it anytime I want.

Knowing it's possible and truly believing in it are two different things.
