Here's my technique for stabilizing and prolonging LDs. As soon as you realize you're deaming, regardless of the situation, slowly and deliberately move your dream body's arms and/or legs, like doing tai chi or conducting an orchestra or treading water. Concentrate on feeling your dream body. Don't look at anything in the dreamscape or any dream characters. Simply concentrate on your dream body and get totally grounded in it. You can also rub your hands together to enhance the feeling.

While you are doing this, repeat the word "Stabilize!" until lucidity is completely stable. This is what I call the "Stabilizing Maneuver" and it works great. You can repeat the Stabilizing Maneuver any time during a lucid dream if lucidity starts to fade or you feel yourself getting distracted or losing focus.
