A question for someone else.

Hi everyone. Ok.. i'll get to the point.

This question does not to be answered for me, but for someone else. There is a lady that asked, "Who is Grimaldi?" and that her real name was Sandra or Sarah Matthews.

She had a dream about her and the lady in the dream said she was important to the occult world. I looked the name up and all i found was pizza, some kind of island (i think) and a families' names. I don't know why, but i really want to help her find out who this lady is. Also i am really curious on who is also.

Any ideas?
