A girl in my class has the same voice and laugh as me. It’s the creepiest thing ever.

So basically my voice is pretty unusual. My voice is extremely low for a woman, which I love because it’s a trait I have that’s unique. However I discovered that a girl in my class has a voice that sounds identical to mine, to the point where I can hear a recording of us and can’t tell who’s who. I likely wouldn’t have given it much attention except that her laugh also sounds exactly like mine. Like to the point where I wonder if she’s trolling me but I have no proof she is. This is the creepiest thing that has happened to me and I don’t know how to feel. Has anyone had anything like this happen?
