Mix OBE with Dreams
Ive noticed that people sometimes mix lucid dreams and dreams with OBE's, and that's absolutely normal.
Sometimes while dreaming your out of your body, and you can shift your consciousness between your OBE and your dream ( sometimes the dream is even lucid ). While your dreaming sometimes your unconsciously out of your body, why not???? Your just not shifted on your OBE. This also explains the vibrations you feel when you wake from a simple dream (can be lucid), and lots of other things. Oh, know the dreams where you feel a very strong sensation of falling???? You really are falling. Just as when you are sleeping with your hands on your neck and dream a person is strangling you, or when you was a kid and urinated on your bed you dreamed you was taking a bath or drowning).. The sensation of falling comes from your astral body floating through your room or falling into your body. Or maybe your really falling form your bed. :) hehehe...
