My mother died in 1978 and two days before she died, she asked me and my older brother what we would do if she died and my mother being was in what the family thought excellent health, not taking her serious, we jokingly replied what we wanted of her estate.
Two days later my mother died of a massive heart attack. My mom had always told me that when she died, she would come back to take care of her plants. My mom was obsessed with plants and had them in every room in the house including the bathroom. The day of the funeral, later that evening, I was laying in bed at my mother's home and only God knows that this is the truth... Suddenly my mother appeared in the very dress I had buried her in. I was not asleep, and from the bed I could see down a hallway and there she was attending to one of her hanging plants that had been one of her favorite plants and she turned slowly, smiled at me and vanished.
The following day my step dad has fallen asleep on the living room couch and had broken a large sea shell that had a plant in it that was sitting on the coffee table. No one knew he had broken it. My sister and I were sitting at the kitchen table and we could see the plant on the coffee table and it moved from the center of the coffee table to the very edge of the table and I jumped up to catch it.
That is how we knew it had been broken. Mom had come back to tell us. Surely Mom was still taking care of her plants.
