ELI5: Why do really light feathers and dust seem to be attracted to people even when you move away?

Air pressure. Really light floaty particles especially are very sensitive to air currents and waves. When you move in a direction, you create a temporary low pressure space in the air where you were. Air rushes in to fill that space dragging light particles floating around in it with the air. This effect is pretty small since humans can't move particularly quickly and our bodies aren't big enough to create a ton of drag, but it's signifigant enough for dust.
