Stephany,
At the time of this dream there is much conflict, hate, anger, disunity and even vengeance in the situation (red).
Your brother is relying on his own abilities, power, strength (hand & arm) and actions in order to sustain himself or achieve deliverance from this situation. He chooses to disregard part of God’s word (white writing) that gives direction, and can deliver him. He is relying on his own strength which lacks faith in God’s help. There is a warning to make him aware of an upcoming attack. His wife treating him with contempt or ridicule (laughing) without remorse (happy about it).
