Is there limits of shifting?

I reading a post a little bit ago about a TikToker who said that if you shift scripting you know spanish that it’ll be a made up language since you didn’t script it here.

That made me curious on if that’s how shifting works. Based on your own perception?

If that’s true: would realities be wonky since it’s impossible to know EVERYTHING? If you didn’t know the laws of physics would gravity be different?

Or is that not how shifting works? Let me know what you think, or have experienced if you’ve shifted.
