I breathed in and out but air wouldn't enter my lungs. Starved for air, my heart raced at tremendous speeds, and my lungs shallowly rose and fell in time. I stood there for what felt like an eternity but was actually only five minutes. Satisfaction of security was nothing but a distant memory , and an invisible force crushed me from every possible direction. Each second submerged in fear made a permanent mark on my heart, and a vivid imagination made me wander whether it was just my mind playing tricks or reality.
