Platonic realm

Okay, so imagine a big world where everything you see and touch and hear is real. But then there's another world that you can't see or touch or hear, and that's where the platonic realm is. It's like a super special place where things like ideas and concepts and numbers live. They're not real things like a tree or a toy, but they're still important because they help us understand and talk about the real things in our world. So even though you can't go visit the platonic realm like you would a playground, it's still a really cool place that helps us learn and think.
