Is There a Three-Dimensional Surface?

I feel like maybe you're saying that there maybe are three dimensions, but one of em, you don't want to call it a dimension. I got nothing against calling it a dimension, but it is different from the other two, right? And so we'd be fascinated to discover our universe was actually onedi sions, with like two weird projected dimensions,. instead of being three dimensions. No, it doesn't change how you live your life, necessarily, or whether you should buy insurance by insurance. But it changes, i think, our concept of the nature of reality.
