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?

Draw a line on a sheet of paper.
Why can’t you lift the line up into a third dimension?
