I've experienced something like what you describe. Sometimes, I get flashes of completely different perspective on something and go "Wow... It's like that?". The thing turns another facet of itself to me, and I can see it in a different light.
It's different from realizing something. Realization comes organically, with a reasonable degree of infallibility. You can somewhat trace it to points in the thought train, even if it's a long-ass path. This, whatever this is, comes at you like a car crash: completely unexpected, sudden and it hits quite a bit with the knowledge it reveals. Maybe it's the same process psychologically, but the effect seems too different.
Does that sound like something you experience?
