Hi Lunatime, I feel that your grandmother is sending you a message that she is with you now ,and that she would like you to wear the ring that was hers. After all you are coming up on the 7yrs that she has been gone. That is probably why you are receiving this dream now. I too often receive messages in my dreams and I try to understand their meanings. I believe they are messages from my beloved that have departed I hope this was of some compfort to you.
