So realistic

This is a dream that I remember so vividly! Shortly after Mother Teresa died I had such a realistic dream about her. I am not Catholic and never really paid that much attention to Mother Teresa but I had a dream where I was in India at dusk and I was in a line in front of this tent where Mother Teresa was and I remember thinking how strange this was since I knew she was dead. It came my turn to see her and I said to her "Is it really you?, how can this be true!" She looked at me laughing and said "Of course it is me! Do I have to hit you up side the head to make you believe me?" Then she preceded to take my hands and bless me. Why on Earth would I have a dream like that?
