Say, let’s admit consciousness is the result of a physical process.
Then say this process only goes “forward” when our time coordinate increases. Just like an egg gets cooked when it’s temperature coordinate increases, but it doesn’t get more or less cooked when it’s temperature coordinate decreases.
This would mean that going back in time doesn’t result in any perceptible change, since your consciousness hasn’t evolved from it’s “former” state.
Thus making it possible for us to be travelling through plenty of dimensions in varied directions, only ever experiencing the brief times when you happen to be moving in increasing time. Or whatever combination of movement along varied dimensions makes it possible for you to be conscious.

That’s just not how science works. One can only postulate a theory, make predictions based on it, and test it. If you can come up with an experiment that shows the model false, it is disproved. Otherwise only if it stands the test of time, and useful predictions it becomes a law - although there’s always the caveat that it could still be proven false.
But you do have to start somewhere, with a framework for consistency and logic, or else you’ll never get anywhere and it’s a waste of time. That the universe is based on repeatable, consistent physical laws is about as basic of a framework as there could be. You can add abstract random magic into your model if it makes you happy, but I think it makes the model considerably less useful. Unless you can show me how it doesn’t, of course.
