OBE's can be obtained during meditation. They're usually thought of as happening when the body is asleep but a lot of people can do them while awake while in a trance state. Sounds almost like you're a natural at meditation and relaxation. Being able to see with your eyes means that you've transferred your conciousness into the etheric body, not the astral - confusing, I know. The etheric body stays closely connected to the physical at all times. This is very common with people who meditate. With practice you should easily be able to transfer from the etheric into the astral body and obtain a full OBE. Next time it happens just picture yourself floating up from the bed or whatever you wish. It should be relatively easy at this point.
Best wishes and good luck,
