Dear Sharon,
Driving a car in your dream always represents you (being the car) and you driving means you are in charge of your life..."taking the driver's seat." The moth getting in is an anoyance to you and eventually, it brought out other fears. I also heard, "Anoyances" from my guides in this for you...and "bothersome". You have some issues within yourself that you are guarding that need to be "let out" just as the moth (represeting those issues)...you wanted the moth out and it wouldn't get out nomatter how hard you tried. You need to release those issues and then the moth, (deep emotions buried inside) will get out of you.
