If you frequently dream about things related to your ex-wife, either family members, photos together, or even quarreling with your ex-wife, I suggest you find a time to have a chat with your ex-wife and have an in-depth chat. Get rid of all the unresolved things.
Another possibility is that your recent life reminds you of the feeling of being with your ex-wife. Maybe life is smooth and happy recently, or maybe life is not smooth recently.
Some people go back on their word after divorce, but there is no way to remarry. Only after the divorce did I find that life was not easy, and I realized how happy and happy life was with my ex-wife. Deep down, I regret it very much. Coupled with the recent life is not smooth, I miss the days with my ex-wife more.
Moreover, some people's lives with their ex-wives are very uncomfortable, and their daily lives are full of quarrels. After the divorce of his ex-wife, life was calm and there was no quarrel. But recently, you have encountered troubles again, and you may have quarreled again in your life.
You hate this kind of quarrelling sound in your heart, which reminds you of deep memories and makes you feel like you lived with your wife in those days. Then, you dreamed of your ex-wife's family, which shows that your heart is full of resistance and fear.
You can compare the above situation and see if it is in line with your present situation. Of course, it is also possible that you saw what your ex-wife left behind that day and printed it in your mind. It is also possible that I dreamed about my ex-wife's family that night. That is what we often say, think during the day and dream at night.
