My advice is to not focus on the physical but if you can on the spiritual. For me, when I go to sleep, it feels like i realized that everyone is sleep, and that i am sleep, and wake up in the spiritual realm, (for me this is the dream realm.) You have to relax though and keep confidence and faith in your seeking ADA. Because it can drive you crazy if it spirals out of control and you can't control it. I feel like ADA is not easy but once mastered, to the point that you do it even when you dont want to, you'll realize that you yourself are sleep in dream because you'll feel disconnected from the world. Because ADA shows you how everything is connected.

I have been trying for a year, and ADA is what I will say I've been chasing after to be able to become lucid. I had my first lucid dream and the above is what best explains the way I became lucid, 2nd to the fact that my God and Lord Jesus Christ gave me this gift and allowed me to awake. All I can say is that confidence in key man, if you have confidence and faith then you will achieve. Don't become discouraged if it doesn't happen when you want though, you just gotta have patience.
