I would invent a Dream Memory Bank. It would be like a pillow, you would sleep on it like an ordinary one. As you dream, it would scan your head for brain waves. Later it would interperate these brain waves and create a video montage of your dreams. You can then store your videos on your computer or something. It is such a far fetched invention that you could only dream about it , but hey, who knows? Oh, and before Bill Gates makes millions on this, I would like to put a patent on my Memory Bank. Just kidding Bill.
