The Possibilities Are EndlessWell that's not realistic...
The ludicrous and often laughable effects the will puts on the imagination often brings us joy and worry, if not to just fill up time, then because the rational can be boring. Pausing time in the midday to just take in the scenario of the next moment with the exceptions of your virtual creativity that can change any mood, partake any talent and take control of or free any convention in society or nature. If even only for a daydream, the imagination creates the inner changes that entertains our soul or at least enough to make us smile, laugh and cry for a reason apparent to no one except ourselves.
If not for fantasy than realism, the imagination serve's its purpose shaping how we chose our careers, vacations, and for some, even religion. To foresee the future to the extent that you visualize the experience, lets your expectations drive your capabilities. However, the mutually capable, stirs the imagination to the point that the future embraces the idea of one mutual mind that can unpredictably shape the possible.
"If" - Really meaning the mind's way of suspending disbelief so that doubt doesn't get in the way of ingenuity - "if" then is the imagination's favorite tool to inspire the body to step outside what it knows so that the clock can stop for a new idea. Although, Ideas are usually concentrated, the imagination is more erratic and improvised like a stream of consciousness connected through memories, reason and kinesthesia.
I guess its really just a matter of having the imagination you actually want, because we can imagine the universe we want, but what is our influence but the universe we live in? If you live as a witness to not having control, does it affect the matter in which you allow the freedom of your thoughts? Or for the ones always in control, does your imagination only resemble what you are used to? Or is it all the desires being manifested through every resemblance?
We often dream of distant lands that differ in ways that seem to be influenced by what we already know, except we can imagine different proportion, size, rigidness and smoothness to any combination suitable for ourself. People do different things to escape either the simplicity or complexity in their daily life. The imagination is that world separate and yet somehow connected to this world. I guess for some, its possible to be trapped in your own head, and for others, hard to ever take the time out of their lives to take a vacation in it.
