Don't do anything, Kvxdelta.

Instead, go with the flow of the dream you're in, letting your dreaming mind do all the complex creation work for you. Simply enjoy the dream you are in, and participate rather than try to take charge. If you're lucid, you'll notice that the dream tends to adjust itself to your expectations without your conscious help, because it (aka, You) knows what you really want. Think of it as expectation-driven creation, rather than the conscious creation you need if you choose to take over the entire dream.

You do run a modest risk of losing lucidity by going with the flow, but only because the dream might become too much fun to bother maintaining awareness, so who cares!
