Ok, I have been doing Lucid Dream training for about a week now. Ive only had 1 Lucid dream and I wasted it from getting to excited and waking up. I can however go into sleep paralysis at will. I hear a lot of things about how Sleep Paralysis helps you lucid dream? I dont understand how this helps?

What do I do once in sleep paralysis? and what are some quick techniques to reach the lucid state more frequently? (I always lay on my stomach, if that matters)
