I have been having similar experiences in various forms since BD. I dont necessarily think it is the universe messing with you - I think it's more that you (or I) am getting in tune with people who are going through similar circumstances.
It also may be - at least in part - our brains attempting to problem solve. There was a person in our lives for a long time, and now there is not. Therefore brain seeks to fill that void.
Or it may just be random circumstance.
I find life interesting (sometimes painfully so) in that regard - things only become clear after you have gone through them.
One thing I started doing that has helped me a lot has been to ask myself "What am I supposed to be learning from this?" whenever I encounter situations or conversations that strike me as interesting or unusual.
I dont get the answer right away many times, but sometimes a few days later I get that "aha" moment.
