If you would like to lucid dream, you should start trying to remember your "normal" dream after you wake up. The purpose of this is: If you can't remember regular dreams, there isn't any way you'll be able to remember if you had a lucid dream. All lucid dreaming really is is being conscious of your surroundings while in a dream. If you can realize that you are in a dream while in your dream, you will become lucid. There are hundreds of different ways to learn to lucid dream. The most commonly used one is asking yourself throughout the day if you are in a dream.
