Classical physics defines the idea of dimension as the volume of an object as well as its position in time thus objects are said to work in 4-dimensional 'spacetime.' 4 that's a nice simple number.

As always things are not always as simple as they first appear. When attempting to explain how our physical universe worked 4 dimensions weren't enough. It couldn't be explained with only 4, they needed more. Theories were made new dimensions were created. Dimensions that cannot be observed but there all the same.

They say that if you were to hop into a rocket ship with the hope of travelling to the end of the universe in the end you would end up where you started, because you can never reach the end if the end exists in a dimension you can't observe.

Have I confused you yet?

The theories the physicists came up with proposed 10 or 11 dimensions. But what if in fact there were more? What if there were hundreds? Thousands? And infinite number of dimensions? And what if one was to observe one of these supposedly unobservable dimensions, to travel in that dimension, what would happen then? Could it be we would travel to a parallel universe? Another plane of existence?

Maybe that's what happens when we die? Our souls exist on a plane we can't fathom and move along that dimension to the next world. Maybe…

Still, I can't say for sure. I don't have the answer everyone expects of me.

What I do know is this. The ground that I'm standing on now is wrong, the air I'm breathing just isn't right. I don't belong here. This isn't my world but here I am all the same.

The big question is how do I get back?

But the most important one is what the hell am I supposed to do here in the mean time?
