Some journeys you take so often that eventually you stop noticing you’re on a journey. Your brain decides the intricate details of the trip are no longer important and your focus shifts inwards to thoughts and daydreams. In my last year of university I took an hour long commute, and most days I’d step onto the train and within the blink of an eye I’d arrive at my stop.
This jump inward doesn’t just happen while travelling. It happens wherever you go. From the first moment you step into a new environment your brain is training itself to block out details for the next time you visit. This is why new environments can create anxiety. Your brain overflows with information and it doesn’t know how to cope. At home your brain can shut off. It knows everything, so you can relax.
Have you ever noticed how a long walk through a new environment seems to take forever? Your mind is so conscious, taking in all the details that you don’t get a chance to daydream. Walking back you always say to yourself “it seemed shorter on the return.” This is because your brain is less conscious of the environment, you’ve already seen it, so you’ve got more time to lose in your mind.
