If you dreamed about having a sibling: You can improve your relationships, but you should also take care of your relationships. To see that someone has a sibling in a dream means that you will overcome your problems easily, and you will get hurt by doing injustice. For a man, this dream indicates that he will lead a peaceful life, be healthy, and work to gain Allah's approval. As a different interpretation, it is a sign for life to progress as you wish, to be sad and to focus on your goals.
