You realize that all your dreams and nightmares are actually predictions of real-life events. One night, you have a particularly horrifying nightmare about an infestation of giant roaches in your house! Do you warn your family? If so, what do you do to warn them? Do they believe you or not? What do you do to prepare? What is the outcome?

And, an alternate: 

These past couple of days, you've been woken in the middle of the night by eerie music being played. Do you tell your family about it? Do they believe you? It turns out that you're the only one who can hear this strange music...why? What happens when you go to investigate it?
