>>11800445the mechanisms that give rise to perceptually bistable images aren't particularly well understood, but there are a number of hypotheses and one is that intrinsic fluctuations in visual cortex that govern 'perceptual inference'** are what result in an ambiguous precept. These fluctuations are amenable to top-down modulation from higher order brain regions.
So in other words, you "trying to figure these out", is your brain attempting to steer the ongoing activity in low-level brain regions that give rise to the illusion. This isn't good or bad for you brain, you can try it all you like. You'll probably get better at it over time.
** Perceptual inference is the notion that we construct (infer) our perceived world from limited sensory input. Our eyes only see so much and it is our brain that fills in most of the gaps in order to determine what is going on in the outside world.
