Do you feel uncomfortable when a stranger tells you he has seen you in the neighborhood/at work or elsewhere several times?

It happens to me with people I’ve never seen and it makes me feel like I am monitored. Last month for instance a cop approached me to (probably) flirt with me and asked me if I go to my college and that he has seen me there before.
Another time a new coworker that told me that we apparently go to the same supermarket but I’ve never seen him anywhere in my life even though I thought I was aware of my surroundings and I like to people watch.
It seems harmless but I live in a big city, don’t look very striking so I’m kind of weirded out that people notice and remember me but I don’t even know they exist. Is this bormal or do I look weird?
