The Interpretation of Dreams says: "If you dream of the death of your closest relative, the person you dream of will live a hundred years", then dreaming of your mother's death indicates that your mother will live a hundred years!
Dreaming of parents' illness or death, the inclination of family property, career and status will encounter difficulties.
There is also a saying that you subconsciously want to get rid of the shackles of your mother and "hope" to leave your mother.
It means that everything will go well and good things will happen again and again. Such as the reappearance of lost things, making up with friends who turned against each other, and so on.
