One night, I had a strange dream of walking around the external perimeter of my parents’ house. After I woke up the next morning, I reflected on my dream. As with any waking life instance, walking around a fixed area means to check out the immediate boundaries. This is done for the purposes of determining threats and surrounding conditions. My dream of walking around the external perimeter of my parents’ house probably means I have to pay some attention to their welfare. I have to take care of their needs, or protect them.
