Finding yourself lost in thought is like venturing down into the deep dark endless muck of a sewer system. Never quite sure when I giant wave of shit will come wash you away to darker, more horrific portions of shit. And hoping beyond hope to be able to identify the gleam of light you entered in at. Praying it will bring you back to the surface, unmarred, but just slightly dirtier. Still capable of cleansing the shit from you, before it finds its way into an open wound, allowing it to seep and fester and open you up to a whole new mental infection.
