Interesting, although I don’t think you spoke too soon.
I’ve noticed something similar. You observe a result, then suddenly a test directly blatantly and literally related to that result comes.
It could be a test to confirm/test who you say you’ve become or just remnants of the old self refusing to change.
But I’m leaning towards the first hypothesis. It got to a point where I refused to consciously acknowledge/write down specific results I’ve observed in passing (not the way to go) just to test it. The confirmation test didn’t come, up until I acknowledged it somehow, then I became certain — I was looking for confirmation for who I believe I am.
Now, anytime I manage to observe it, I try to recognize it as so, and, make a conscious decision to give the evidence I’m looking for.
