Dreaming of a band as a group of musicians suggests harmony within the Self. All parts of the personality are integrated. If the image of a band is that of a stripe, there is some limitation within your circumstances which needs to be recognized, and you may need to work within well-defined guidelines. There is harmony on a psychological level which you can access. However, this requires practice and imagination. A band of material or stripe may be highlighting a division between two parts. If, however, the image is that of a group of musicians, this would indicate the need for teamwork. Also consult the entries for Orchestra/Orchestrate and Music/Rhythm.
