Aha. That's certainly possible. Many people have a habit of criticizing someone behind his/her back. For example, many people are addicted to gossiping about coworkers. If that's what happened, then she is not the worst kind of person, because the worst kind of people continue to talk to you in a friendly manner while harshly criticizing you when you're not there to hear it. In your case, she pulled a mean face at you and avoided you. Therefore you know she doesn't like you. This is less bad than not knowing.
Alternatively, maybe nobody backstabbed you, rather she observed your body language or your manner of speaking, and she decided that you're different and "not normal", and then the discrimination center in her brain was activated, causing her to feel negative emotions about you, causing her to want to avoid you for the rest of the night.
I asked one of my associates about that girl (her name is Meghan) not liking me and they said "I have not heard anything negative about you from her".
Coincidentally after I asked my friend about her Megan started talking to me and acting a lot more friendly
