Okay, when I had just started to attempt astral projection, I got to the vibrational stage. I never quite made it out though, so I kept trying each day. Eventually, I would get to the vibrational stage much quicker! But by now, after days of practicing so long, I never get to the vibrational stage any more. Yet, I've gotten so good at concentrating I literally think of NOTHING else while attempting to go astral. I spend much longer and don't even push myself so I honestly don't know what's the deal. Do you guys have any advice?
Also - when I used to get to the vibrations, sometimes they would just wear off. I've heard vibrations mean you are really about to get out from some people, and simply a stage that's supposed to come to pass from others. So, I don't know which one's correct... it's all very confusing!!
