I don't think you're crazy at all. And I would like to take you up on your offer. You said you need a question that only myself and the deceased person would know. Here it is...
My mother passed away in 2000 and about a year ago she came to me in a dream. She had another person with her, who was the person who came with her?
If you need something different or want to pass, just let me know.
Thanks
Betty
