Unlike dust that float then settles in fine layers a miglie is a slightly larger particle but still small enough to engrain into a carpet, rug or clothing.
One characteristic of a miglie would be that they slightly jump almost lifelike if you run your fingers through the carpet, rug or clothing fibres.
