Looking up, insomnia, notice dust on the edges of the ceiling fan blades. Get up, get a stepladder and some wipes, I clean the fan, fixture, and blades. How is it so dusty? The blades are loaded. Why doesn't the dust fly off when the fan is on? How does the dust get up there? Dust should stay on the floor where I can vacuum it up.
If dust under the bed is dust bunnies, then what is this? Dust pigeons.
