The dreaming process is seemingly always running, like a twenty-four hour movie theatre in some dingy street. You can slip into it in a moment with no sense of shock and emerge, slightly dazed almost as easily. It's not as if there are two different selves, but the same self engaged in very different tasks. It is clear that even the most objectively consistent world is a kind of achievement, the result of complex intentions. The exact same intentions are found in both the dream world and the waking world, but they are developed very differently in each case.
