At 2:02 today, it will be the third minute of the third hour of the third afternoon of the third month of the the third year of the third decade of the third millennium.
Like, yesterday was Thursday, but today is DEFINITELY a Thirds-day.
Almost everyone [94%] has intrusive thoughts, but people respond to them in different ways. The key difference between people who do not struggle with their intrusive thoughts and those who do, is not that the former do not have them (although they may experience them less frequently and intensely), but that they are able to dismiss unwanted and upsetting thoughts as meaningless. Those who struggle with intrusive thoughts tend to attach great significance to the thought, and worry that they really do believe or feel those things, or really would commit those acts.FWIW I have AT LEAST my fair share of intrusive thoughts, but they are readily dismissed.
For me religion said, there's Objective Truth. And later the multiplicity of religions told me people are just guessing at it. But that means I'm deeply anti-authoritarian; ANY truth is only valid relative to it seeming like a probable good match for the Objective Truth, and that includes whatever random crap my brain comes up with.
The French call some of that "l'appel du vide", the call to the void, the unbidden urge to hurl yourself off a high place (which my grandfather had literally, but nothing ever came of it.) Less literally, it's a good framing for a lot of thoughts of weirdly dark possibilities. I went to a lot of antique-y and artisan stores with my dad as a kid, and I remember saying something like "wouldn't it be cool to spin and push and smash it all down?" and he was like "uh... no."
