Trapped in his outer body experience, a pro lucid dreamer cooperates with his skeptic rivals to wake up before the league organizer reaps their awareness.

Would you consider an extra line for the world?s setup?
Here?s a random attempt:

In a lucid-dreaming competition, the commonly despised champion must convince his competitors to cooperate with him to escape the imaginary world created by the game-master, holding their consciousness ransom.

What's the difference between a "pro lucid dreamer" and a "lucid dreamer"?

I have? a very vivid dream life including lucid dreams but "reaps their awareness" is vague; I have no idea what that means, what the story is really about.? (And lucid dreaming is an in body experience.)

fwiw
