I think you have too many exceptation how wild should happen. You only need relax your mind and body while keeping awareness. I used to have this problem. Even if i kept my mind completely silent nothing happened because i was waiting sleep paralysis and focusing too much on being awake. Its very hard to learn the relax completely but dont try to wild same way over and over again. Try to find a way how to keep just enough awareness for you to fall sleep while not completely blacking out. Once you have done it twice it becomes easier. What worked for me i kept just repeating myself ``no worries, just fall asleep, just relax`` while keeping awareness.
