Buy a blank book or a notebook with a particular journal topic in mind and keep this book for only that topic. You may decide to keep several kinds of journals at the same time, so remember that you do not have to journal every day.
You have to care about your dreams if you want to remember them. Before sleeping think about dreaming, and tell yourself that you have to remember your dreams because they are very important, trying to fix them in your conscious memory as soon as you wake up, without thinking about anything else.
Dreams are one of the ways in which we can live more purposeful lives. By paying attention to our nightly dreams, we receive guidance and information that helps us to live a more deliberate life by pointing us towards more conscious choices.
