Your journal is susceptible to being read by someone else, especially if you keep it out in the open. Or give everyone a journal. If your family is curious about your journal, let them have an experience of keeping their own journal. Make it a family project to keep personal journals for a month. This can help to raise everyone's awareness of the importance of privacy.
Dreams can be important for self-analysis and personal growth.
My intense two-month journaling project was triggered by a lucid dream. In some cultures, it s common for people to share dreams. In our society we tend to have the attitude that dreams don t have much meaning. But dreams can provide amazing insights not only into our psychology and personal problems but insights into science, art and sports as well. The chemist Kekule reported that his Nobel-prize winning realization of the structure of the benzene molecule as hexagonal rather than straight came after dreaming of a snake grasping its tail in its mouth.
