How does dust get everywhere?

Question

You go into a room that hasn’t had folks in it for 10 years and there is dust everywhere. I thought it was skin cells but obviously not.

Even rooms with no access to the outside have dust.

Indoors most dust is dust mite feces, they eat your dead skin cells. Anywhere humans exist, dust mites exist. It’s kinda gross, I don’t recommend googling it or thinking about it too much. I’m surprised I didn’t see anyone give you this answer yet. Outdoor dust is mostly random particles like people are saying (pollen, sand, spores, etc) but indoors . . . .
