When you dream about your brother being in danger, it might indicate a feeling of helplessness or fear for someone close to you. In some spiritual traditions, such a dream may be a warning sign, urging you to pay more attention to the well-being of your family members. In Hindu dream interpretation, it may symbolize the emotional or physical vulnerability of the dreamer’s family members. Alternatively, it could represent a fear of losing someone important in your life. If your brother has been facing challenges recently, the dream could be a reflection of your anxieties or the emotional state of your relationship with him. This type of dream might also represent unresolved issues or stress that you're carrying.
