If you belive in the native american traditions, the moth is a sign of transformation. A coming into your own if you will. It is much like the butterfly. Do a google search on "moth totem" and you will get a ton of info on it. The native americans believe that if an animal/reptile/bug/whatever visits you in a dream then it has significance. Look up the properties of each one that you dream about and it will guide you towards the meaning in your own life.

Just my .02 cents anyway...lol
