A stranger sat you down an hour ago, and explained that you are going to be killed by Death himself in exactly 63- no, 62 now- hours. He says he's a specialist named Sam Winchester. He says he can help.

"You have to trust me. I saw it happen. It was in my dream!" he whispers to you.

Why should you believe him? He could by lying... he can't actually be a psychic- right?
