Sure, it’s true that a Dream Journal increases your dream recall and makes it easier become familiar with your personal dream themes, but the writing itself can actually trigger lucidity.
I think this was exactly what Rathez stated in his “Tutorial: Beginners Guide to Lucid Dreaming” thread a few years ago.
Another thing that could be interesting to try out if you feel you have the time is to treat your real-life days as dreams, and try to recall as much as possible of what happened during the days, while also writing in your Dream Journal at the same time.
This should in theory blur the lines between waking and dreaming and perhaps make it easier to bring your Lucid Living mindset into the dreams.
