Day Dreaming

Neurologists and psychologists have taken a deeper look into day dreaming. We day dream when we are not given something to focus on. Other parts of our brain become active and causes the day dreams. The reason is not really known yet. It could be a way for the brain to stay active and alert in a sense. It could also create a sense of coherence to one's past, present and future. So instead of avoiding day dreaming maybe we need to do more of it.
