Is it possible to dedicate your sleeping hours to creating a consistent-dreaming environment?

From time to time I find myself revisiting the same places in my dreams, only to find them more elaborate and often more populated than before.

Is there some way, like how we encourage our minds to recall dreams, to recall specific places outside of reality, and to step equally between two worlds rather than what we know as our waking life and the many mixed and wonderous dream-realities we know?

What would it take for any of you to create such an existence?
What changes would it make in your waking-life if you held an equal existence in another?
If you created such a world... what would it take to bring someone else into it?

Give me your thoughts on this.
I'll be starting tonight; somewhere between 2am and 4am PST.
You'll find me by a decaying stone archway, surrounded by dense forest.
