I was thinking about Alana Mareva's power (from The 4400). For those who don't know about it, she can make people experience very realistic alternate realities. These experiences inside the dreamworlds can last from hours to years; but from the perspective of the real world, they only take a few minutes.

That, of course, reminded me of lucid dreaming. What if you had an LD spanning several years? What if you could dilate time enough to grow up, find a job and settle down, or build a city, or become an legendary hero from scratch, in only one night? Do you think it's possible?
