"What do you mean, not real dreams?"
"Just as I said. They're not real. In here you can only go so far. It's like a training ground, preparing you for the life you'll live."
"After all, nothing you can do here changes the world. You can see that, right? This place is solid, unalterable, but you may pass through it back to the land which is alterable, taking your lessons with you."
"After all, the dreams you dream at night aren't real either. But you can still learn from them."
