How would you know the difference between the dream world and the real world?

I had a dream last night about tracking down Johnny. In real life, I hope he's OK. We were trying to save him right before I left to come back to the Philippines. He had inherited his brother's gang trouble. And I wonder if Emmanuel has succesfully been able to sue the pigs (crooked cops) who molested him. Ah, worrying about matters back at home.
