Loved ones showing signs of still being there?

I've had so many instances of my grandmother showing me she was still there long after she past away. I am examining other people's stories of their loved ones passing away to do an essay. As part of my research, I'm asking to hear your stories of loved ones showing that they are still there. I'm all ears, and to be honest, I find these stories very comforting, as it is easy to feel crazy about these things happening!
