I’m overwhelmed in most crowds. A daunting stroke of everyone chipping away at my personal claim for sentience engulfs and consumes the hitherto fine rhythm. To infect me as it seems, with foreign DNA and spread their own selves beyond the boundaries of their physical origin. Akin to a pop-up ad with a primary objective to gain access to my mind, occupy and exploit the precious resources of computation my senses voluntarily invite. In conversation we actively filter perception and discriminate information and thus there is at least partial control over what we choose to assimilate. Obtrusive thoughts may have a similar effect, as if these brain worms have their own views on what the purpose of the colony ought to be. Meditation comes to mind - an obtrusive thought par excellence.
