The last Oracle

Lex wakes up in a moonless night, in a forest that shouldn't exist.
Thinking it's all a dream, he ventures into a world he assumes will cease to exist once he wakes up, but even when he goes to sleep, he doesn't wake up, suggesting that he's either: Stuck in a dream; Hallucinating; or worse, stranded on a hostile world with no way back.

Now the biggest problem he will face is not waking up, but rather whether he's going to be a monsters next meal.
