What does it mean when you dream of your deceased grandmother as a child ?

Iv had a few random dreams of my grandmother since she's gone. So does it mean something when you dream of her as a child? I remember thinking she is so beautiful when I was looking at her in my dream. I had another dream of her a while ago. I was looking at a pic of her and she was smiling at me and I was so happy. So what does it all mean anyways thanks x
