I did, it was a long process tho. I've been told I had acheived it in a leangth of time that in almost impossible, but I can tell you how I did it.
1) You'll need a journal. Everyone astral projects in their sleep, but to control it is another story. First to understand the astral projection you need to remember your dreams. It sound cheesey, I know, but it really works. Every night before you go to bed, say to yourself "I will rebember all my dreams and wake up after every one" It is possible to have more than one dream in a night, I myself recorded 5-6 three nights in a row. Now after you wake up, write down your dream and go back to sleep.
What is the perpose of this? Well if you remember your dreams and then record them it is easier to notice patters in where your body astral projects.
2) After about a month of practicing this, comes the hard part. Right before you fall asleep yo need to focus relly hard on where you think where your body will decide to astral project. Doing this will keep you connected to your conscience mind, so you have control over your actions. Once you are out of your body, and you have landed in a new astral plane, yu can begin to explore.
3) Once in the new place you must, I reapete MUST stay calm. Thinking about what could happen to you like being attacked by evil it will happen, you are more vaunrable in your astral body, thinking of evil only attracts evil. But if you ever feel lost or scared think of your home or your body and you wil be there in a flash.
4) You are ALWAYS connected to your body by something called an astral cord, this cord is there to give you an easy way back to your body and keep you from losing yourself in the astral planes. Two things can come from your astral cord from being broken: 1. If your lucky, your astral self will snap back to your body and you will never be able to astral project again, or 2. You will be lost forever in the astral planes and most likely never find your body. Even if you think of your body, you wouldn't be able to go there because you are not connected to it. Your body will be in a coma untill you die.
For more questions just shoot me a message. Sorry for the longness...:P
