Airborne Dust Bokeh

This was captured about a couple of feet from the ground in our bedroom. I asked my wife to be the hand model. As you can see airborne particles are highlighted under the natural light from the window. They form pretty bokeh however. I just couldn't believe how much dust there is even though we have closed all our windows in this bedroom and we are far away from the city. Just an experimental photo shoot when I am not at the wildlife refuge.
