Dreams about exes often symbolize unresolved feelings and emotions from that past relationship. In this dream, the fact that you spotted your ex's building while in the car with your mom and brother suggests that there may still be some lingering thoughts about that relationship.
The fact that you consider visiting your ex's house, even though it was nothing like his actual home, may suggest that on some level you are still trying to reconcile with the past and perhaps find closure. It may also indicate a desire to reconnect with your ex, or at least to have closure on the relationship.
The fact that your mom defended you against your ex's mom blaming you for the breakup may suggest that deep down, you are searching for validation or support from those who are close to you. It's possible that you may be seeking reassurance that you did not do anything wrong in the relationship, or that it wasn't entirely your fault.
Overall, this dream may indicate that there are still unresolved emotions surrounding your previous relationship. It may be helpful to reflect on these feelings and consider ways to address them and find closure.
