Explaining Our World and It's Dimensions

It's easy to see life as though we only had length and width, probably because this is how the majority of us draw, or perhaps a better term may be "doodle". In any case, the downside to drawing like this is that the landscape is often hard for our little stick figures to get below or above it. This is one of the best examples of what it would be like for us to live under these conditions; and if you really think about it, there would be no stairs or even poles, because none would ever be able to go around them.
Lessening the freedom even more, no one ever thinks to draw in one dimension. That's because it's like trying to draw a graph with only the x-axis; there's no fun in trying to do anything in an area with a line as your full spectrum of possibility. Look at it this way: if a friend of yours is on the other side of a paper clip, you are never going to reach him.
Moving on to the dimension of time, this could be compared to the past single-dimensional area idea. But instead of many people on this line, it is one single time unit, never changing in speed as though on a conveyor belt. Now think of that line becoming two dimensional, then three dimensional.
