Interesting. The movie, "Se7en" was about the seven sins. Moths represent many things but in particular, we associate moths with an eating away at fabric (moth holes) but we don't see the damage until it is too late. What unseen thing/person is eating away at your fabric of life? Something is trying to put holes in your self-image (clothing).
Consider the traits of a moth: *They flit to artificial light. Moths by nature use the moon to navigate by but man-made lights confuse them. *They are fragile and short-lived. A moth, after it transforms, usually lives only about a week. It is also at the end of its lifecycle so look for an older person in your waking life who might represent this dream moth.
Moths could represent older people or old, musty ideas.
