What should I do?

So, I don’t have very long, but I have a story and I want your thoughts.

So: Yeaterday, my best friend called me, and once I got out of class, I called her back. We were just chatting as I was driving home. Then, I noticed a little piece of paper in my wipers. I told my best friend I was gonna pull into a gas station to see what the note said. (Usually when people get handwritten notes, it’s generally a “screw you, you parked horribly” or something of the like” I pull into the gas station and see this note: “Sorry I hit you’re car :(. #BadLuck”
So I FLIP OUT. But I get out of my car, and see NOTHING. No paint, no scratches, NOTHING. So I go home, and I tell my mom to come look at my car. She doesn’t see anything either. So, I drop it. I’m like “someone probably just thought they hit me, or they just flipped out because they door dinged me.” I go about my day and go to rehearsal, thinking nothing of it. THEN walking out of rehearsal around 9 or ten, I see ANOTHER note on my car. It says: “Sorry, you we’re in the way... tapped your car again :(. #BadLuckx2. P.S. I’m in theatre two. (They then crossed out the ‘w’) I get your struggles. Friends..?”
And I am BAFFLED. Because yet again, there’s not a scratch on my car. I’m so baffled, and I really don’t think anyone hit my car. My mom thinks someone might be weirdly trying to hit on me. Cause how on EARTH does this person pay close enough attention to me to know what I drive? Also, if I had hit a car earlier in the day, I’d avoid that car like the PLAGUE. I’m just so confused. Like, what!? And maybe I’m just overreacting and someone really did just manage to hit my car twice in the same day, i don’t know. What should I do? Should I just let it be? Should I do something about it?
NOTE: BOTH OF THESE INCIDENTS OCCURRED IN MY SCHOOL PARKING LOT BY THE THEATRE BUILDING****
