Paranormal activity in grandmother's house since her husband died?

I would say it is her husband reassuring her he is not gone and will be there for her. He is not intending to scare her, especially the email. What did it say?? Spirits in limbo often don't want to leave loved ones behind, and I'm surprised he doesn't try to sleep in her room with her. My grandfather often feels my grandmother in his bed when he is missing her particularly. He is merely making himself known. You should try talking to him? Telling him about whats happening in your life. I'm sure he'd love that.
