Best Seller! From the dreams of Emily!

In this one, we have some kind of time traveler from the future. To prove she's from the future, she's trying to predict events for her friends and family. One such event is the flood in New Orleans, and then she realizes she doesn't even know when it will happen. Her lack of knowledge on current events and history leaves her in a pickle as she tries to get help to get back to the future. Her predictions are usually half-right, half-wrong, and people start to wonder if she's got something loose in the head.
