Lets say that there is a lucid dreamer out there that has been lucid dreaming since their childhood. Since that dream was able to lucid dream for so long that that dreamer becomes very skilled. Skilled enough to create an entire world from scratch, then populates that world with cities, urban sprawls, people, and creatures. In doing that the dreamer gives each of those people and creatures, a personality, physical/personality traits, pet peeves, lifestyles, etc. Now that dreamer has created a fully living world, what is that dreamer to do?

That dreamer decides to live in that world while sleeping in waking life, but the dreamer starts thinking. Things are boring or going to get boring soon, what should the dreamer do? The dreamer decides to take the world he/she created and create problems for it, such as: gangs, occasional riots, dangerous wild life attacking citizens, big monsters intending to destroy the city. All the things that needs a hero to come in and save the day, or a villain to take control. But then that itself will get stale eventually, because ultimately it is the dreamer that created all these problems to begin with. The dreamer no longer wishes to know what comes next so he/she relinquishes their power to know what they create therefore not knowing what comes next. It instead will feel like deja vu.

The dream has created a world with so much life it is bordering on being a full second life. With the dreamer now dreaming in seemingly blissful ignorance of whats going to happen they are now content. But that person knows that they're still ultimately dreaming because all they did was renounce their ability to know what they create in the dream but not the dream itself. Eventually the dreamer chooses to let go of their knowledge that they are dreaming all together, but with a single phrase that knocks them back into action again as a precaution if something dire happens like: "This world is mine!"

The dreamer has treated their world every night as if it were a new episode of a television series with themselves getting into all kinds of hijinks, saving the day, etc. Maybe even an epic 4 part series that tie in together, like tonight is going to be part 1, and part 2 will be tomorrow.

What I want to know is if all that I stated above is possible for a single lucid dreamer to do, is it possible for a dreamer to do such things to the extent that I explained above? Has anyone of you been able to attain to anything similar to what I explained?
