meeting the dead.....

When I was a child, no more than 7 or 8, I had a really strange dream about a mysterious lady. The dream was so real that when I awoke , I had a hard time trying to figure out if this had actually happened. I finally told my mom of this dream, it started out in a building that was not one that i had visited, or at least that is what I thought. But for some odd reason, I was waiting on the elevator. When the doors opened, an elderly lady was in the elevator and she moved to the side so I could come in. After the doors closed, this lady said hello to me, it was not that she said hello, but it was that she called me by name. Ok, I don't have an ordinary name which is why this freaked me out. So I turned to her and asked, if she knew me, and she replied that she knew all about me, in fact she knew about me from the beginning and she couldn't wait to see me. Then out of the blue, she hugged me, but while hugging me, her nail scatched me in the side, and that is when I woke up. So after telling my mom the dream, I started telling her that the lady had long black straight hair, and she looked like she was maybe Indian , She had on a long light purple dress and had on a necklace made of white pearls. My mom looked at me like with watery eyes. She had explained to me that the lady, was my Grandmother, who Died when my mom was a child. She was buried in a Light purple dress and pearls. My mom could not believe what I was saying, and although hard to understand, she did not dismiss my story . To this day, where the lady's nail had scatched me, I have a mark, which appears to be a mole. I did not have this prior to that dream.

Could loved one who are no longer of this life visit the living?
