Girl who rejected me in college 5 years ago approached me and said I look familiar and asked if I went to school with her, why lol?

Some girl that I’ve seen a good 15 times in the last 5 years after the rejection suddenly approached me and said that I looked familiar to her and brought up school from back then. Did she really forget that she rejected me when I asked for her number or she playing dumb? I’ve seen her around at least 15 times in the past 5 years and never talked
