The All Pervading Darkness

When I was a kid, there was a door that linked our living room to the hallway that branched off to the bedrooms. At night when I needed to take a leak, I would always glance at the crack between that door and the wall, just to check if there wasn't anything lurking in that gap. I guess I wasn't really scared of the dark, but of the possibility that something was hiding within, waiting for me to be off my guard. After taking my leak, I would walk briskly back to my room and it was all I could do to keep myself from slamming the door. I was afraid that whatever was lurking there would be following me back to my room. Sometimes I would even feel a presence behind me and I would basically run back to my room and cry myself back to sleep. That door became the bane of my existence as night fell. Every night before I went to bed I looked around the corner of the door just to check, despite the fact it kept me awake during the night.
