Twin?

So ever since 8th grade I have been having a weird feeling that I have a twin sister. There was a girl in my class that looked similar to me and when I saw her I was thinking 'wow, it's like I'm looking in a mirror.' I can't tell if she is my twin or not. She's really nice and outgoing and I'm shy. We've talked before but I get nervous and I can tell she does too. She is the one I have talked about in my previous story. She is adopted from Russia, even though I was born in Duluth, there's still a possibility we are twins. I feel like I can predict anything that's going to happen to her.

I'm in 10th grade now and she still goes to my school. When we look at each other we usually look away right away. I can also feel her emotions like if she's mad I'm mad and if she's sad I'm sad. It's really weird. I recently had a dream that she was in my house and she called me sis. And we always hung out and wore the same clothes.

Also whenever someone talks about her in a bad way I get defensive. I barely know her but yet it feels like I do. I know a lot about her. It's confusing. Even if we aren't twins, I feel like I have a twin out there, like there's something missing in my life. Could someone help me find out if this girl is my twin sister or if I do have a twin brother? I feel so lost right now and I would love some help.
