[Goosebumps] In “The Beast From The East”, where exactly did the kids end up?

They’re walking through the normal woods, not that far from their campsite.

Suddenly, the plants are weird and otherworldly, there are strange animals and there are Beasts. I’m pretty sure that the sky changes color, too.

Is this really just an isolated part of the woods? If not, where did the kids end up? Is this another planet, another dimension, some sort of fairy realm? Were they deliberately brought here, or was it just a “slip through the cracks” event?

It's been ten years since I've read these books, but presumably there was a natural portal to another world.

It probably wasn't intentional by some powerful being, but rather these things naturally occur sometimes; think of in Alice in Wonderland, where the portal to Wonderland just naturally occurs in the woods in the form of a rabbit hole. It's not horribly uncommon for various portals to other worlds (be they planets, realms, or dimensions) to just appear in otherwise innocuous places, and they may be temporary or they may be permanent.
