What does it mean to dream of roaches?

I've been having dreams with roaches lately. so i look this stuff up. And the meaning seems to fit..it means that you need self-cleansing of your spiritual self. You need to confront certain fears or things that you have not gotten over. If in the dream you step on the roach and kill it..thats a good thing. you're making progress. this of course, is if you're scared of them..in the dream. if you see them and seem not to care, there are problems around you but they don't seem to mess with your life.
