I've only had 2 lucid dreams but sleep paralysis and me go way back haha. Of course stay still no matter what. If you feel like moving don't! It your mind testing your body to see if it is asleep...(your mind and body fall asleep seperatley) if you move your body any when you feel the urge to it's basically telling the mind that "I'm still awake". If you remain still during this urge to move your body your mind will be tricked into thinking your body is asleep and you will enter sleep paraylisis. Your mind will begin to dipp in and out of your subconscious...if you remain conscious thru this...bam you just accomplished a WILD. Try to count your breathes passivly during this process...it may help. And sorry if this is confusing I tend to not re-read lol
