Answer 2

There are ways to remember your dreams--and even to guide them. One way is to keep a paper and pencil by your bed. When you do dream, write it down--just a few words is usually enough. In the morning, read it and you'll probably remember most of the dream.

If you are subject to nightmares, when you wake up with one, think of a less scary ending. Say it to yourself over and over as you fall asleep again. You'll be surprised to find you can actually guide your dreams.
