Recurring dreams about a former classmate, especially in a romantic context, can symbolize unresolved feelings or nostalgia for a time in your life that felt simpler or more carefree. The warmth and sense of belonging you experience in the dream suggest a longing for connection and affection, possibly reflecting a desire for closeness in your current life.

The wave of sadness upon waking indicates that while you cherish these feelings, there may be an underlying sense of loss or unfulfilled desire for that type of relationship or connection. It might also represent a yearning for the emotional safety and familiarity of your past.

Consider reflecting on your current relationships and emotional needs. Are there aspects of your life where you feel disconnected or lacking in affection? This dream may be encouraging you to seek out deeper connections or explore your feelings about love and companionship in your waking life. Engaging in activities that foster social bonds or revisiting friendships from your past could help fulfill that sense of belonging.
