neighboor lying on the floor in the corridor, next day take a cab and cabdrivers son has identical name with neighbor

I live in a 8 story multi-tenant apartment house in the city. One day I heard something outside my door, I opened the door and there was my neighbor from the apartment across my own, lying on the floor with a man and a women that I don't know helping him. I asked if I can help [this neighbor is middle aged and I think he has some mental issues but I don't know exactly what he has or what happened]. The women replied [rudely] for me to close the door because it 'disturbing' or something [I am not in good terms with this neighbor because he is not an honest person and has done a few bad things in the past but when I saw that he was in a bad situation- I wanted to help. Plus- that women doesn't even live there (perhaps his relative?) that was rude of her.]. Anyway- the next day I took my car to the yearly checkup in the garage. It took a few hours so I walked to my mother's house and on the way back I took a cab. I sat at the back seat and there was a placard with the name of the driver [this car belong to...]. I realized the last name was the same as my neighbor [this is not a very common name in my country]. The driver was just telling me about the time when he traveled abroad and left his previous car with his son, and the son had an accident [when the streets were slippery after the first rain] and totaled his car. I asked him if his son's first name was Michael [my neighbor's] first name- and he said yes, but they live next to each other in another city. I told him where I live and about the neighbor with the same name as his son. He told me he actually visited the [small] street where I live to come to the apartment of some family members a few months ago to console them after a cop shot and killed his wife [a story that was in the news a few months ago]. I don't know what to make of this. man[neighbor] in distress- I want to help but receive rudness-driver's son with same name as man and was at my street visiting family that went thru a tragedy. Some people would say it is all randomness- but I don't view reality that way [although I am a student (academically) of science etc.]. I think the fabric of reality is much more complex [but inherently simple at the same time] and connected in seemingly infinite ways...
