Dreams involving ex-partners and their families can often reflect unresolved feelings or past experiences. In your dream, your ex-girlfriend's father hugging you and crying could symbolize a longing for emotional connection or closure, particularly related to your past relationship. His sadness may indicate feelings of loss or regret, perhaps even a desire for forgiveness or reconciliation.
On the other hand, your ex-girlfriend's mother being cold to you may represent feelings of rejection or unresolved tension from that relationship. This contrast between the father's warmth and the mother's coldness could highlight conflicting emotions you have regarding your past and the relationships involved.
Consider what these figures represent in your life and how they relate to your feelings about your ex-girlfriend and the end of your relationship. This dream may be encouraging you to address your emotions, seek closure, or reflect on how past experiences shape your current relationships.
