Newbie and wondering about old dreams I've had......

[sgbenge]

I am just starting to look into astral projecting...I have wondered about it for years, but just never thought I could do it.  Lately, after reading how to do it, what happens, and all about it, I wonder if I have actually done it and not known it.  About 6 or 7 months ago, I had a VERY VIVID dream that I was flying over trees and going to new towns.  I can't quite remember the whole dream, but I have always tried to figure them out.  So, I told a friend about this particular dream, as well as about 15 or so more that I have had, she wrote it off as me just having VERY strange dreams.  It's always like me flying sometimes so fast I can't believe, and then I seem to run into people that I recognize, but can't believe I'm seeing.  Then it just makes me remember strange things that used to happen when I was younger with me seeing my mom (while we were both sleeping) and I always wrote it off as a ghost, but I wonder if she did this too, and didn't know it.  I know that I have always had times during awake stages that I zone, but the whole time my mind is completely blank, and I don't know very many people that have that kind of concentration.  Also, when I was younger, I used to have the feeling of "disappearing" just during various times during the day, sometimes it would be while sleeping, or just during activities when my mind was blank.  During these times I can remember, it was almost like I was above my body and could see everything that was going on.

Anyway, my question is, is it possible to AP without even knowing and also, is it in anyway genetic or related to astrological signs...by the way, I'm a Pieces

Thanks!
