The problem with objective reality is 1. it changes. 2. it can be different for different people in different places.
If I live in rural India, there is probably not a tiger behind the bush. If I live in downtown Chicago there is almost certainly not a tiger behind the bush. This leads to the hard problem of probabilistic thinking which requires a lot more energy than black and white thinking.
Lastly, humans are real, and even incorrect belief systems create a reality you have to live in. God, for example, is almost certainly not real. Saying that in a forum will have some percentage of people downvote you and try to reply with a relatively poor argument. Saying it in the wrong place and time outside of the internet can most certainly get you killed. So just because something isn't real doesn't mean you should open your mouth at an inopportune time and learn the reality it created.
You are overthinking this. Reality exists in a point in time and space, same point where you are. That is the only problem you face.
As much as you would have aspirations to be a pro soccer player, badly enough broken leg can prevent you from ever being good enough.
Your imagination of being pro player does go away when in reality you’re not fit for the purpose.
Pain is part of reality. Suffering comes from wishing reality was different to how it is.
Not to say that knowing this difference has no merit, just saying that it has limits to how much it can do. After all, reality can also hit the brain, when it gets flooded by hormones and neurotransmitters that take away your rational thinking.
Better approximations usually score you more points, which is why our perception usually evolves closer to reality.
Bad scoring systems exist.
For example, let's say if an extremely privileged person – a favorite son|daughter of a billionaire – takes random chances and people around him|her always agree and accommodate for them to win (because they want a favor from a parent), than this person will most likely have a very warped sense of reality through no fault of their own. Basically their only approximation could only be "Do whatever, just don't touch fire with bare hands and don't make daddy angry"
On the other hand, the suffering child from "The Ones Who Walk Away from Omelas" would also have warped sense of reality, because they lose no matter what action they take. The only reality approximation they can know is "everything feels bad"
Sidenote: in my philosophy, the continuous warping of reality happens mostly to people in overprivileged and underprivileged positions. Which is why I believe that a good equality index makes for a healthier society. But thats my pov, I'm not trying to sell it or anything :)
Note that I wrote "continuous warping". While sometimes bad approximations got rewarded more than good ones, reality is probabilistic. Since it can't be comprehended by people, we basically define reality as "something that is more likely".
And that's the answer to your question. If you tune past the reality, you start scoring worse again, and turn back. It's a distance thing, and the goal is to get as close to zero as you can, doesn't matter from which direction.
