Nine in a Day

It's not there in my horoscope. I don't understand it, but in one day I had some kind of run-in with 9, count them nine, persons from my past. I'm talking about persons who I never expected to see again. I'm talking about persons who I never even think about. I mean a woman from college, ten years ago, who I only remember because she ran off with my boyfriend at the time. I'm sure she doesn't even know who I am. A woman who once rented an apartment from me and made my life a living hell, suddenly she shows up at my dance class. Some people I used to work with in various jobs, suddenly there they are in the grocery store. These people are just coming at me from out of the blue. Shot from the cannon of the past. All in a single day, for no apparent reason. Is it good? Is it bad? Is it meaningful? Is it a cosmic joke? Is it dangerous? Should I consult a professional of some kind? If so, what kind?
