Can’t tell if girl has feelings for me or is just being friendly.

So I (22/M) share classes with Claire (21/F). I just have this gut feeling she has feelings for me but I’m just not quite sure, but I’m also oblivious to girls making hints towards me.

So We both commute to school and park in the same spots as each other. I noticed for the past 3-4 weeks that she’ll get there slightly before me and she’ll wait in her car and then once I arrive she gets out and she just seems pretty happy to see me.

She also does this thing in class where we make fun of our Professor and whenever he says his common phrase or terminology, we both look right at each other and laugh a little and smile. This has been going on for a couple weeks now.

We made a bet to see which phrase he would say more in class the other day and since I won she had to buy me gum. So the class after this we were walking to our cars once class ended and she said she had a surprise for me and to come to her car and once we got there she said “close your eyes” and then showed me the gum and just seemed happy and excited to give me the gum bc she remembered how I used to love Juicy fruit gum.

Lastly, she’s been playful with me. And I’ve been playful with her. She’ll mess around with one of my Google docs and then I’ll mess back and she’ll say something like “try me again I dare you” and does other playful things. She’ll tease me for being a picky Eater or she’ll say “(my name) loves nuts” which is an inside joke we have. And she’s done other playful things .

My friends in the class have noticed the “chemistry” between Claire and I as well and have joked that we will get married one day.

I’m just wondering if any of this means anything. I wouldn’t be playful, teasing and do the other things she’s done unless I had feelings for them. Of course, this isn’t the case for anyone but I just feel like “something” is there.

TL;DR: Unsure if girl from school likes me. She does things to make me believe she possibly likes me and I have a feeling she does.
