For the past few years I have had strange dreams and still do. I decided to finally do something about it. Sometimes I have dreams that are possible (Like a book, nonfiction). These are the ones that sometimes happen later in the future. They aren't really warnings or signal, they just show the future. Like I yesterday i wa watching "House", and my sister came in crying and my mom yelling. Then it hit me that I have seen this before, in my dreams. So what could this mean, what should I do, and should I be worried?
