You push and you pull but you'd never know

Funny sometimes, how a calm surface can dissemble so completely the swell of activity below. How a lake, without a single ripple to betray it above, can continuously host the boisterous lives of the fishes, frogs, and Snorks below. But gazing at it and seeing nothing, I still know that the storm of life always churns in the depths, whether or not it is witnessed. And I still know that the storm rages on behind your iron curtain, whether or not I bear witness... but has your conflict escaped your own notice completely? Does your struggle take place safely beneath the surface in your subconscious, where thoughts of me are kept sequestered? Unaware of it as you may be, you must at least be aware of its byproducts — lack of sleep, fatigue, mental exhaustion... come to think of it, this is starting to sound somewhat familiar. Like Dicrocoelium dendriticum, I crept up in you and I wouldn't let go.
