What does it mean if my crush knows my name but I never told it to her?

So I sat with my crush at lunch today and we were having a really good conversation. She seemed very interested and was smiling and occasionally giggling but then I asked her what her name was and she told me, then I asked her if she knew my name and she knew it right off the bat. This confused me because this was the first time we were actually talking besides a communtiy service event over two weeks ago where I literally spoke one sentence too her. But I never told her my name. I followed her on instagram over two weeks ago and she followed back but I didn't think she would know me through that. When I asked her how she knew my name she smiled and said I think I heard someone call you that before, I'm really good with names. Is it weird she remembered my name, or a coincidence? We're also in different parts of the school so our friends don't even know each other either. Need opinions.
