For anyone interested in mastering the art of lucidity in their dreams ( becoming a successful lucid dreamer ), one must understand the importance of keeping a log or journal (diary) of ones dreams. Not only does it stimulate the memory of your dreams, but it gets you in the habit of having a relationship with them, and wanting to remember them. Remembering is the first step towards becoming a lucid dreamer because even if you were having lucid dreams, if you don't recall them then it will be as though it never happened. In the next paragraph I want to clarify what a lucid dream is because it seems to be a hard subject for some people to grasp, because it seems so out of the realm of possibilities, but it's not.
What is a lucid dream?
A lucid dream, is a dream in which you realize that you are dreaming, WHILE you are dreaming. The realization that "this is a dream" must happen while you are IN IT, CONSCIOUSLY. That is what a lucid dream is. It may sound UN-scientific, like folk lore or b.s. to some, but it has been scientifically proven. A researcher named Stephen Laberge has proven the phenomenon of lucid dreaming. He's a researcher for the Stanford University Sleep Research Center. He's published some great books on the subject, which I will be selling here in my shop, and he also founded a great thing called the "lucidity institute".
How to Lucid Dream
There are many creative ways to help induce a lucid dream. You need to develop a relationship with your dreams and make a habit of recalling them first. I highly suggest buying some books on the subject because I found that feeding my interest was a very big factor in my success with the art. You will need to develop a habit of questioning your reality, that is, am I awake, or am I asleep and dreaming. This is key because if you never wonder if this that we call reality is a dream, then how will you ever know? A simple method if to occasionally look at your hand. In a dream you may have more than 5 fingers, or some of them may be out of proportion, or something of the like. Flip it around, and really look at it. This method works for me often. You can also turn a light switch off and back on again. Things like this are different in dreams. If you can will yourself to fly, then you're definitely dreaming. You'll get the hang of it! I highly suggest one of my favorite books of all time called "Dreams Of Awakening" by one of my personal heros, Charley Morley, and "The Dream Dictionary" by Tony Crisp, another great hero of mine.
