I get the idea of dimensions of reality and how there are eg infinite two dimensional planes in our 3d one. What I don’t get is why they can’t be moved between. In a 3d cube we can draw a 2d line between any two points by changing the direction.
Applying this to reality, if we exist in a universe with more than 3 dimensions, why are we unable to change the “direction” we are in?
I’ve often heard extra dimensions described as planes but why can we not change planes in the same way a diagonal line would. Is it because the concept of a higher dimensional direction doesn’t exist in our lower dimension?

How do you know we don’t? It’s our perception that is locked to four dimensions. Since we are only able to perceive in four dimensions, any action in additional dimensions is mapped to those four in our perception— we only see a slice of it.
So if you’re wondering why we can’t change our direction in time, that would be because we don’t know how to perceive that change, and we can’t visualize the next dimension out.
And any changes we make in spacetime still need to adhere to the laws of physics.
