There is a possible explanation for the schizophrenia example. My wife did a google search for a particular medication that person had been on and went off of.

There is a possible explanation for the schizophrenia example. My wife did a google search for a particular medication that person had been on and went off of. That was a couple days prior to the ads showing up. So good old Google could have been part of that - not sure how google searches affect facebook ads - or perhaps it was the pages she visited to read about that medication. It's all just f-ing creepy sometimes regardless of how it come about. It sure seems like verbal conversations being overheard is a part of it.
