His pulse quickened. He could feel the hot blood rushing through his arteries, his blood pressure rising with each erratic contraction of his fibrillating heart. His chest was heavy and tight, suffocating on the carbon dioxide trapped in his lungs. The world had closed in around him. He was alone in a great void, a black hole where energy went to die. The darkness pulsed around him: silent, menacing waves of emptiness, loneliness, and eternal suffering. He opened his mouth to scream, afraid his voice would be lost to the void. Before he was able to vocalize his terror, his mother opened his bedroom door, apologizing for forgetting to turn on his nightlight before having closed the door.
