It happens to me a bit. Even before Scn involvement.
I remember once seeing in my head at work the footage of the Challenger exploding after take off. I went home and watched the live telecast of the launch and saw it explode exactly as I saw it. I just stood there with my jaw dropped, not just for the tragedy of it either. That was perhaps the most memorable one for me.
What usually happens for me though is that I will think of someone or something and within the next few days it will come up in front of me, even if I haven't seen the person for a long time.
I'm not even going to attempt to explain it, other than it ain't scientology related at all.
I only ever had one 1 hour auditing session and barely completed the HQS course before I walked away.
My missus can do even stranger things, which I won't be going into here.
Lots of strange and unusual things go on in this world that seem to defy explanation, both good and bad. I really think it is a stretch to peg it onto scientology. If you are a scientologist, you will attach it to the tech working (or whatever) and if not, something else.
The mind abhors a vacuum, and will normally attempt to fill in the gaps when there is no obvious answer.
EDIT to add: The above video explains a little bit about the mind/vacuum thing. Whilst that is a legal story, it works in all sorts of other ways too.
