“I shut my eyes in order to see.” -Gaugin

Does the world become a smaller place as we age or does the imagination over estimate?
Have you ever walked into a place you had not been to in a few years and thought; its smaller than I remember. I recently went to a place that as a child I thought was very big and intimidating. Proportionally the height ive grown to cannot be the reason for which it now looks smaller. When we are young are our dreams bigger than reality? Does that mean that our imaginations and by association our dreams are bigger than what is really existing in reality?
Dreams are supposed to be bigger than reality of course or they wouldnt be dreams, but - are they still achievable if you have an over compensating imagination?
