Dreaming of brothers may represent the feelings or blood relationship between brothers. Dreaming of my brother's waist may imply that he may have encountered some difficulties or physical discomfort in real life. But the specific meaning of dreams will vary according to individual circumstances, and only dreamers can better interpret the meaning of dreams.
In short, when interpreting dreams, we need to consider personal background and situation, as well as other details in the dream, so as to understand the meaning of dreams more accurately. If necessary, you can consult a professional dream analyst or numerologist, who has more experience and professional knowledge.
