Is It a Good Idea to Have a Dream Twice?

Joseph is not liked by his brothers because he's a bit of a rat fink. He also has the daughter of the favourite wife, which isn't working in his favour. And there's an idea too that if god sends you a dream twice, he really means it. So i don't know if that's true. Although i do know that people have repeating dreams and might be true that that a dream you have twice is really trying to something home.
