Shared Dream

Hello,
My mother had a dream last night where her deceased cousin's father-in-law came to her and gave her a big hug and was happy. In the dream my mom knew he was dead and was kind of freaked out that he is hugging her. She didn't know him too well, and hasn't thought of him since his death 11 years ago.
Concerned, my mom called her cousin and told her about the dream. She had a very similar dream that night. In her dream the father-in-law came to her and gave her a hug and said everything was going to be just fine. She too rarely thinks of him.

What can this dream mean? It cant be just imagination or coincidence.

Thanks,
Phil

My thought is that, is exactly what he said, it's going to be fine. Is anyone suffering from anxiert or stress at the moment?
