If you dream of a white moth, it can foreshadow an illness that proves difficult to avoid, even as you search for someone or something to blame for it. For a woman who sees a white moth fluttering through a darkened room, it may reflect unmet longings and a restlessness that quietly diminishes the joy of those around her. If the moth drifts through the scene and then vanishes — or settles somewhere final — it may carry a somber message about the passing of someone close.
