If simulation is possible, we could upgrade reality to 4D

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.
*A fourth dimension can be time.
Time is a very convenient choice for a fourth dimension, but "fourth" is purely namesake. There's no reason we couldn't describe our world in our three familiar spatial coordinates with an additional coordinate for ~~temperature~~, for example. We just don't easily conceptualize it that way because it feels less contiguous according to how we currently frame our model of reality.
Disclaimer: my sources include internet research and far too much time to think. I'm absolutely open to discussion and new ideas in whatever form.
Edit: Temperature is kind of a bad example at face value, but good conceptually. Hopefully I'm communicating my point at least we'll enough to be comprehended.
