When engrossed in a book or film, have you ever felt what the characters are feeling? Did you empathize with their plight? Or maybe you got lost in the moment?
There is a suspension of your reasonable mind that would continually pull you back to reality and the fact that you’re sitting on your sofa, and that everything in that novel or movie is artificial, and everyone is pretending to be somebody who they are not.
I hate fiction books (for the most part) and I don’t watch movies so I don’t often get wrapped up in characters like this, but apparently, it happens.
However, there is great value in this suspension of reality when it comes to creativity. If we can suspend the parameters which bind us to "the way things work" while we live in the real world, we open ourselves to the possibilities that previously only a young child would think were plausible.
While visiting that “open world” of possibility, you will become a million times more creative and more interesting, too.
Then it’s time to switch on the reason and logic and find a way to structure things to build the idea that you’ve come up with.
As a side note, this is just one reason why I'd be a horrible doctor. You don't want a doctor who's too creative and disconnected from reality. He can permanently disconnect you from reality.
