When you leave your material body in eg. Astral form you two remain linked by something that looks like a silver cord.In AP theory it like the ambilical cord - link betwean mother and child, and it is endless.When you leave the body it remains there but with lack of better expression i would say trapped insade a grey shell which is as i understood a shell that protects your body angainst the intruders (defensive mechanism) so i think that there will be nothing to fear.This i've got from a book i read by Robert Bruce, and he said when he first tried to enter his own body back the Shell wouldn't let him inside.he enter back by falling into his body.E.G. Q: ever had a dream in which something is happening and you for eg. trip and fall, but in the moment you should hit the ground you wake up with sensation that you have been dropped onto your bed?
Your astral body was in astral realm but floating some distance above material body.in astral you were falling down (your astral body) and eventuly merged with material that resolved the waking.
You can search Internet and look for books by Robet Bruce. I know one of them is availbe to download in .pdf form.
Wish you all the luck!:
