When you sleep and have reached R.E.M. sleep, your mind wanders and produces wonderful visions that you may or may not remember when you wake. We use this sort of journal to record what you remember when you wake.
Perfect for those in therapy or who would like to follow their dreams. Use your dream journal to self-analyze or seek professional help to analyze what you see, smell, hear, or do in your dreams.
You may, through time, remember more of your dreams as this sort of tool will promote dream memory that will increase as time goes on. That means you will also remember more about your dreams, and you can record even more detail.
