Try doing it standing up. It helps if you are relaxed that doesn't mean you have to lie down for it. Nor do you necessarily have to close your eyes. Just be mindful of your surroundings. Don't do it if you're driving a car. Do at the very least keep a seated position, not lying down when recording to the recorder and imagine you are talking to someone. You will want to listen to the recording to debrief.
