Dreams involving ex-partners often reflect unresolved feelings or situations from the past. Being on the roof may symbolize a desire for perspective or a feeling of being above a situation. Throwing a brick at your ex and his sister could represent feelings of anger, resentment, or a wish to express your emotions regarding past experiences with them.
The act of throwing the brick may signify a need to let go of negativity or to confront unresolved issues directly. Falling down to the street could symbolize a confrontation with reality or consequences of past actions.
Consider what emotions you felt during the dream. Were you angry, empowered, or remorseful? Reflecting on these feelings can provide insight into your current emotional state and help you understand any lingering issues related to your past relationship. It may be beneficial to find healthy outlets for these emotions, such as talking to someone you trust or journaling your thoughts.
