Thank you Nadir. You make a lot of sense. Perhaps the broken rosary may mean I need to pray the rosary correctly? As for the nun Sandra, I don't know what to say, I do not know anyone named Sandra, but she was cheerful.
For the other two dreams, the first one is this:
I was outside my deck, I ran down the stairs, turned to my left up towards the sky, there I saw Our Lady as in the Miraculous Medal. She moved her arm and tossed to me a white towel with two blue stripes at both ends if it. The moment I caught it, the dream was over.
The second is this: in my home, I looked out the window, andOur Lady moved through the house, again as in the Miraculous Mmedal, picked me up heading towards the sky. I heard a voice, cannot remember if it was male or female voice, but said, "God is going to introduce you to a girl." The dream ended there, did not say what girl or for what purpose?
