Welcome to Gaia! ::

what's the difference between OOB (out of body experience) and Astral projection? if they are same people can have OOB even if they are walking and some people said if someone moves the body person can slingshooted back to body and even die?

i'm confused <.<

OOB is feeling of your spirit going out of body.
Astral Projection is your spirit leaving the body and going into planetary outer space or something, or maybe going through different dimensions.
your spirit is always connected to your body as the body is still living, and no, you don't die from it.
and in a way, when you die, your spirit enters same state as astral projection.
so consider that when you die your body is non functional, so spirit can't get back in but it enters another body.

OOB is basically meditating and you feeling your spirit leaving your body.
One can meditate on a place they've been or want to go and feel themself there, or imagine it. Thats what it Out of Body Experience.
Astral Projection is the actual thing, it requires more concentration, and focus, and quietness. In Astral Projection or Astral Travel your spirit is actually out of you. and if you travel to far your spirt can end up staying out, thats why you must be experienced meditator to do this.

An Out of Body Experience is more or less where you literately are out of you're body but you don't travel to any of the astral planes. You just are there. An Astral Projection is where you cross over to another plane and travel around.

As for the whole "you'll die if you get moved", I think that's pure crap. All that will happen is you crash back into your body and you wake up. That's it.

Others have said that an OBE is accidentical. But I don't think so. Because I've accidentally astral projected and gone somewhere else. OBE can be willed as astral can be, but because you don't/didn't go anywhere it would be better to call it an OBE. If you want I have a dream encyclodipeda (sp?), and I can get you a somewhat official definition for the two.
