In theory, your dreams are changed by the amount of attention focused on particular aspects and entities of the dream.

If you could get yourself into an area of pure white - and then bring in a DC you may want to 'interact with' , or an object, would it be possible to not focus on the surroundings as much since they are nonexistant?

Secondly:

The world we live in is governed by a set of rules, eg. gravity, our minds workings, physical limitations etc.

Would it be possible to create a set of rules that our minds associate with the dream world, that we could force ourselves to learn, and operate under every time we have an LD, and partially in RL, in order to create a permenant stable dream world.

Once the normal dream incorparates these rules, when we enter an LD, we would have to spend less time stabilising everything, and more time experienceing the dream.
