Last night, my mother dreamed of a friend of my father who had been dead for many years. Then, my mother gave the candy to the other party, and the other party didn't say yes or no. What do you mean?

I don't think it's necessarily the dead man.

Maybe your mother will meet a classmate or friend she hasn't contacted for a long time, and this friend or classmate may ask your mother. Of course, your father may also know this friend.
