Like russmi said: Between being awake and falling asleep, your mind enters the hypnogogic phase. In this stage you begin to lose touch with the world around you without showing the physiological stages of sleep. Pictures form inside our heads like still or moving pictures and although you may have never noticed them, they are there. It's the stage where you actually start to dream but are still awake- you will see pictures in front of your eyes (as opposed to in your imagination) and if you focus on them you'll be pulled into then as a regular dream. In this state you still can pull back your mind to stay out of the dream, or jump in and fall asleep. You can "watch tv" or dream. This is the phase, which can bring you into the OBE state. Or fall asleep.
