Madam ... I do not know who you are, but I assure you, Mjolnir is very real, at least to us. I am Norse, and we grow up with the stories of our gods. While my own situation is ... confusing at the moment, with the dreams, and I can at least tell you that I am Sif, and I am Norse. If you need to know anything about our gods, I place myself at your disposal.
