I would say they are basically the same. I consider myself to be in AP when i become totally aware and in total control of my surroundings which are usually some place unique. In my OBE's i tend to think I am getting up out of bed only to realize that my body is asleep as my spirit is not. I usually discover the difference when something odd happens. Then I say to myself."Oops, I think I'm still asleep, physically." One can AP after they initially OBE.Your just mentally projecting yourself some place other than your origination. Happy Astraling!
