Ants in a Dream

Hello esteemed Rabbi, my mother, may she live long, dreamed that she was told to open an envelope. She opens it and sees many ants coming out and disappearing. On the other hand, she sees someone chasing her and she is anxious, then sees her son (who is married) telling her not to worry because it is just him and giving her a protective ring. She says she has one, but he insists that she should take it and says it is a different ring. What does this signify? I would appreciate your response.
