if you want to learn how to AP go on google and look it up if you dont know the site here it is www.google.com
i tried to find results on my questions and didnt find any someone help me please
Well since you claim to have tried, i'll answer your questions as best i can, although take note that i've never actually been out of my body before.
People who are clairvoyant, or "in-tune" with the astral may be able to see your astral body, but those who aren't probably couldn't see you.
Yes, you could project with a friend and you could both see each other's astral bodies.
I can't answer the last question.
Remember though, the best way to answer questions like these is experience. Once you can project you can answer all of these questions yourself, and gain a much better understanding of the answers.
By the way, this is really the wrong section of the boards to be asking these questions. The proper place is probably the OBE discussions section.
can someone tell if people awake in the physical world can see you in your astral body???can you and a friend astral project and see each other???and can you enter peoples dreams in ap??
