In my opinion, In pure $2$th-dimensional space, There is 2 movable ways.

enter image description here

And in pure $3$th-dimensional space, There is 3 movable ways.

Am I think in right way?

Any answers will be appreciated, thank you.

Added. Here is what I'm thinking about "Real Space"

enter image description here

Two dots are particles.(such as electron)

The lines which they release is quantized.

So it can be measurable or comparable distance between two dots.

In $N$ dimensional space there are $N$ basis vectors, and hence $N$ "directions".

    @Eric: yes, but this is not about what is really true, it is about what effects manifest themselvs in our normal lives. In particular, I am **not** saying that extra dimnsions do not exist. I am saying that they don't have any noticeable effect on the macroscopic world, just like the curvature of the Earth has almost no effect on scales smaller than a few miles.2011-07-18
