one technique i use is simply trying to go to sleep in a position I hate and wouldn't want to go to sleep in to get into paralysis. once im paralyzed and aware i then try to astral project. Problem is that everytime i feel the vibrations and actually start leaving, I get nervous and say ok thats enough, stop. The next time I try, I will go through with it and then record my experiences. My worst position is lying on my stomach, works like a charm. Hopes this helps anyone
