Everything and everyone in this town...

it's all nothing more than a figment of our imagination?

Not so.

When someone has a dream,

they temporarily become able to cross over into another dimension.

And do you know what happens when you go to another dimension?

You gain the ability to fly, to explore fantastic, never-before-seen places,

and even relive the past.

You experience many things that are impossible by common sense (in reality).
