Each night before you go to sleep, tell yourself: tonight I will remember my dreams. In the morning when you first wake up, try to remember what you dreamed. Write it down in the handy notebook that you keep by your bed. The more you record your dreams, the easier it will be to remember them. Just jot down the day and very briefly, what the dream was about. After you’ve got a list of dreams, look and see if there are any themes.
