What is the meaning of someone seeing a crown or tiara on another's head when there was none?

I was having sort of a get to know each other conversation with an acquaintance at her home. As I was about to leave she said that she had never seen anything like it, but that she was seeing a crown on my head. When I said, a crown, she said it was like a tiara. I then asked her if she might be seeing my aura and she thought that it was possible. Anyone have an idea of what if any symbolic meaning there is to this?. Only serious answers please.
