Please explain to me that I dreamed that my husband was getting old.

The plot is not detailed, but dreams generally reflect people's inner desires, so it is possible:

First, your husband is not mature enough, and you want him to become mature.

Second, I have a bad relationship with my husband and want to end my marriage as soon as possible.

Third, lack of confidence in yourself. I hope my husband can still be kind to himself when he is old.
