More than just a technique, a dream journal is a core component, a fundamental, of lucid dream practice. A dream journal acts as one's personal "map" of the dream world and is an indispensable tool that every lucid dreamer should possess.

Dream journals can come in many forms; from a physical notebook to a digital record. More important than the medium used is the data that it collects and the regularity of record keeping.

A lucid dreamer without a regularly updated journal finds themselves in a position no less impaired than a cartographer without pen and paper, or a scientist without a means to record data.

I would try to do it each morning, shortly after waking, transfer any dream memories and relevant factors from your night's sleep into your journal. If required, one can either use a voice recorder or shorthand system to quickly record key points that can be transferred, in full detail, at a more convenient time later in the day.

Note: It is not required to use the DJ system here unless you are going to do the lucid tasks, "The TasK Of The Month or "The TasK Of The Year". The Link for that is down in my signature.

The more data collected the better, beyond a record of just your dreams, additionally recorded data, you can (and should) also record your: sleep times, sleep quality, distractions, level of health, techniques used, sleep environment, hormonal cycles, diet, sleeping arrangements (partner/alone, etc.), and any other relevant factors.

Also, Before sleep, You can use your journal to note any dream goals or intentions for the coming night.
Regularly assess your dream journal for recurring patterns, clues to any lucidity triggers (either from within the dream or external factors), and to become familiar with the nature of your dreams. These assessments are a time to categorize and update your list of dream signs, improve your familiarity with the dream world, search for recurring patterns in your sleep, assess the effectiveness of different techniques, or be creatively inspired by your dreams.
