Pain After Having A Lucid Dream

I had a dream about my ex deceased husband all night long last week when I woke up my ring finger had a sharp shooting pain in it. I felt like screaming, I took off my ring and it stopped. I was married to him for 14 years at age 17. We divorced and I remarried he drank himself to death, the night he died I went to say my goodbyes at the hospital, that was 11 years ago in the dream I had we were getting back together and I had a long blue dress on that was the color of my wedding dress, I told him that I hope that this works out this time because I really love you. Then I woke up. When he passed way that night he came to me in my sleep and kissed me on the lips and said he had to go now, I always feel that he is with me in my heart, any help to understand what is going on! Thanks! I have had dreams in the past and they have came true but it is happening more and more these days, and also I have had an experience that my husband now didn't turn on the coffee pot in the morning and came out to the kitchen and it was not on, but I want to know why I experienced the pain in my ring finger after dreaming about my ex all night long, he was my first love and the love we had was a deep deep love it was a abusive marriage with a lot of drinking and drugs but it really was a deep love we had for each other, I need help to understand this experience... Greatly appreciated thanks

My mom has always been that way when she dreams something it usually does happen my daughter also has had dreams that her dad and I have gotten back together she is 34
