Surely you must have read Carlos Castaneda's books right? Because what you described is exactly how he describes the energy body, and those books are ALL ABOUT manipulating that energy.
That bright glow of awareness is located somewhere behind the right shoulder blade, right?
I only managed to see energy once, but it happened at a bad time, in the middle of a concert, surrounded by people.
so basically what you want to do, is prove to yourself that what you are seeing is real and not just a figment of your imagination. i am not certain wether you will be able to manipulate this energy for OBE's, however you can indeed manipulate energy. i dont recommend you start messing with peoples auras though, as that would just be energy vampirism. if you want to experience the energy i suggest you try some form of healing. when you heal you channel energy, so when you feel it go through your body it might strengthen your trust in what you are experiencing.
i too see the white glow around people/plants/objects, this is the etheric body. i have seen colours too in the right light conditions. usually dim light with a plain background is best. i have seen tornado shaped energy vortexes coming out from someones crown chakra and balls of energy around peoples heads. i am still developing my auric sight, but this is something everyone can learn how to do, and many people see this, so you are definetily not imagining it. again, healing comes to mind, although this doesnt require seeing the energy, and im sure others will give you more suitable examples.. nevertheless, healing would be a provable energy experience. you can get attuned to reiki for example and channel the energy. i suppose you could use this for your obes, but reiki is not manipulatable in the sense that it just flows where it is needed, you cant tell it what to do. it is a great practice in 'letting go'. if you want to know more about this, or how it works, just let me know. i hope this helps a bit.
I'm not sure if this is a valid answer to the question about channeling your energy to OBE, but energy raising has been the most effective technique for OBE that I have found (the full-body circuit, and also the body-bounce awareness exercise.) I don't really consider this channeling energy to OBE (or maybe it is) but it has helped me to gauge the type of projection I am going to attempt when I get to the exit sensation stage. If this is not what you are looking for, that's fine-if you want more info about this I'll be glad to add to it.
