@denisafrisk,
I used to see 289 all over the place. 289 being closely associated with my first car, a 1965 Ford Mustang with a 289cc V8 engine.
Of all my anxieties and neuroticisms, this wasn't one of them. Just saw the number in a license plate or a book page, etc... and noted it then shrugged it off.
"[W]hat [does] this mean[?]"
Nothing. Good grief, you're worrying about the most coincidental coincidences to ever coincidence. No disrespect but you might need therapy... not because you're noticing a random repeating number but you just might have bigger picture problems in terms of mental health issues.
Getting help for unresolved anxieties ain't a bad thing. And sometimes getting help and being willing to get help can also be a necessary thing. Don't wait until whatever unresolved issues you might have blows up into something permanently unresolvable.
As an aside? Welcome back since your only other post being 2014. Don't be a stranger.
