Think about it: the Upside Down is a mirror image of Hawkins, Indiana. But it’s been abandoned, decayed, and covered in a slimy, organic goo. It’s like the world’s most neglected basement, and you forgot to throw out the leftovers from 1983.
You’ve got the same houses, the same schools, and even the same Castle Byers fort. But everything is dark, cold, and covered in that weird, pulsing vine stuff. Why is it so fascinating? Because it’s a horror version of home—and home shouldn’t feel that way.
