Anyone want to learn more about lucid dreaming?

I'm doing a kind of visualization technique when I go to sleep and I repeat about 100 affirmations before I fall asleep. There are two kinds of lucid dreams. The first kind involves only seeing moving pictures in your mind like on a cinema screen, which can be fun and even informative, allowing a person to learn more about the recesses of their subconscious mind. The Second kind of lucid dreaming involves having a lucid dream in which case you really feel like you are actually PHYSICALLY THERE! It is the second kind that I'm trying to learn and master. I've heard about how people who've learned 2nd stage lucid dreaming have gained fantastic advantages over their lives. There are people who learned it so well that they could switch on their genes, change their appearance, heal themselves, etc. They can also FREEZE TIME inside their dreams and stay in their dreams for very long periods of time. I've only done second stage lucid dreaming several times in my life, and hopefully soon I'll have it mastered.
