An elderly lady keeps telling me that I'm to marry Prince Harry and that in a past life I was Napoleans wife?

Once, in an Xmas card, she asked me why I hadn't put God Bless on her card and that she said I wasn't brave enough to. She seems ok in the mind, but comes out with unusual things sometimes. She'll draw stars and shapes as well on cards. I don't know what to make of it. Sometimes she'll say that she's the mother of God
