My mother told me of the dream she had about my grandfather, her father-in-law. He came to her one night. She doesn't remember what he said but she does remember how mad she was at him. She was still angry when she woke up. Two weeks later, my sister lost her 23yo son in a car accident. Mom thinks that Grandpa came to warn her. My sister was his favorite grandchild and she would need her mother more than ever. Mom has thought of that dream often because it was so vivid. It's been a year and a half now and my sister is still having a hard time.
