Was she interested or just looking because I was?

I’ve seen the same girl a couple of times on a club night out- she’s definitely my type but I worry that I’m just being Narcissistic. Anyway, the last time i saw her out I caught her gaze at least a few times, it was weird? I turned around and she was looking at me too and then when I went to the bar and looked over she was giving me eye contact too… idk I always over think things. I didn’t approach her because there was some drama with a friend near the end of the night so wasn’t in the mood for pursuing any one haha. I also worry that I was just drunk so much more confident and cocky than usual. But yeah- could she possibly have been interested? Thanks
