Dreams about brushing hair can often symbolize a desire for connection, care, or nurturing. In your case, brushing the hair of a girl may represent a relationship or emotional bond you have with femininity or a particular person in your life.

The shift to brushing the hair of a boy, especially one with dry hair, could indicate a change in your feelings or relationships. Dry hair might symbolize neglect or a lack of vitality, suggesting that there might be aspects of your life or relationships that feel unfulfilled or in need of attention.

Consider what these individuals represent to you. Are there any current dynamics in your relationships that might be reflected in these dreams? This could be a prompt to nurture certain aspects of your life or relationships that feel dry or neglected. Reflecting on these themes might help you gain deeper insights into your feelings and connections.
