Try this metaphor:

Your brain is a movie theater. When it's in use it's all bright lights and gripping soundtrack and shiny shiny. But once in a while you have to chase out the Observers and shut down the projector and then go grab a hose and ruthlessly flush out all the tracked-in mud and popcorn remnants and stepped-on gummy bears and who the hell knows what other gunk.
