You reminded me of inception movie when you said dream within a dream :P
Hey i know about it! My father happens to it very much! He dreams about his friend and when he call him his friend replies that he talked about him yesterday , its one of two , neither they met accidently in astral world while they dont know , or neither it was lucid but became astral , i dont know it very well but thats MY OPINION
Lucid dreams are easy to control , actually use what ill say , in lucid if you want to fly for example and you dont know how , then fear that you will fly!! Fear as much as you will cry and you will see yourself flying easily!! Some lucids i have was seeing a zombie runnings toward me , i was like..shit what will i do!!! , i know its lucid but still was scary as he was running!! I got afraid that im powerful and i feared myself more and more and then i saw myself having darkness wings as ((tekken game )) in devil jin :P , so its all about your mind , if you cant then just fear and it will work totally ^^
Yeah i know! It really helps the body!! Oh did you know this thing too!! If you want this technique to work more , the second time you sleep fear yourself that you are getting paralyzes!! You will get them instantly because of your fears!! , try it out ;)
