Dust

Dust has settled on my computer keyboard over the last week and i'm not exactly sure how it gets there or where its come from. Its kind of like all these little particles get together and become a blanket of dust. They don't just come all at once but seem to get together over a period of time and just know how to get together to create a blanket. They provide a film which eventually becomes a complete blanket holding on to whatever they connect. They have different characteristics and consistancies but you always know what they are when you see them: dust.
Dust has an uncanny way of affecting the unused, the left behind, the stagnant. I'm not sure how this works on my mind, but a blanket of dustlike material has an almost eery effect on thinking. Things drop into my knowledge base over time and eventually gather together just like dust having an effect like that blanket to direct my thinking in certain ways, not necessarily always in the direction I would have my thinking go. Dust on the mind. A blanket of items which are almost like refuse from the myriad of information I take in each day from technology, from conversations, from fallout from the clouds of peripheral information.
Dust clogs things up over time. One skill to learn is not necessarily how to get rid of all the dust but to rearrange the dust so it becomes useful for the imagination rather than causing a stagnancy.
Dust probably does have some nutrient value for growth but needs to be placed where it can have a positive rather than negative effect. In the same way dust on the brain needs to be harnessed for a positive effect rather than left as a blanket of obstruction. What are the items in my mind that have a destructive effect rather than a constructive process and how can i rearrange this 'dust' of the mind.
