Really the best place to go to get answers to these questions is http://www.astralweb.org

You can read about other peoples experiences, exercises to try to project, read forums and ask questions and get answers from people who have have been projecting for a long time.

It is the best place for this type of info.

Non-calming music won’t get you far, but calm ambient stuff with no lyrics might, especially if it contains binaural beats – google hemisync metamusic for more information on that. If you put binaurals on an ipod, use apple lossless format for best results.

You might meet other people or you might not, it depends where you go. I didn’t initially but often do nowadays. You don’t have any limits as to where you can go other than your beliefs – if you have trouble getting anywhere specific just try again another day, you usually discover it’s possible eventually.

I’ve been out many hundreds of times over the years and have never had the slightest problem with getting stuck outside my body. The real problem is staying out of it long enough to explore. The slightest noise or movement will send you back to your body so don’t worry about that!

Ecclesiastes 12

1 Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;

2 While the sun, or the light, or the moon, or the stars, be not darkened, nor the clouds return after the rain:

3 In the day when the keepers of the house shall tremble, and the strong men shall bow themselves, and the grinders cease because they are few, and those that look out of the windows be darkened,

4 And the doors shall be shut in the streets, when the sound of the grinding is low, and he shall rise up at the voice of the bird, and all the daughters of musick shall be brought low;

5 Also when they shall be afraid of that which is high, and fears shall be in the way, and the almond tree shall flourish, and the grasshopper shall be a burden, and desire shall fail: because man goeth to his long home, and the mourners go about the streets:

6 OR EVER THE SILVER CORD BE LOOSED (see link below), or the golden bowl be broken, or the pitcher be broken at the fountain, or the wheel broken at the cistern.

7 THEN SHALL THE DUST RETURN TO THE EARTH AS IT WAS: and THE SPIRIT SHALL RETURN UNTO GOD WHO GAVE IT.

Why? Because "spirits" and "astral travel" aren’t real. There, I said it.
