Dreaming of reuniting with an ex is both positive and negative sign as per dream meaning and interpretation. The dream means other people who had neglected, ignored and insulted you in the past will realize your value. It also means people who had left you will return back after learning about your success. Dreams of reuniting with an ex and you seem happy in the dream then it is a sign of happiness and peace in life through proper decision.
Dream of reuniting with an ex and you wake up terrified or
sad means you will be forced to revisit your past and you will not be happy
doing it. The dream also means others forcing you to do something you are not
sure about.
Dreaming of reuniting with an ex and you are not seen in the
dream means you will hear positive news about your ex. It also means you will
be missed by your ex during a crisis or important event in near future. It also
means you might be jealous about new achievement or current relationship status
of an ex.
Please note that thinking or talking about ex during daytime
or just before going to sleep and then having the dream has no meaning. The
dream will only have a meaning when it happens naturally without any kind of
daytime influence.
