Random debris.
Scrappy debris with black specks, fibers embedded in it.
In addition to weird random debris, I am covered in black specks, black fibers on my skin. Every night when I wash my face and use a cotton pad to clean my face before I wash, this is what it would look like. And at first you would think, oh it's fibers from clothes, but no. This would happen when I wore nothing black or if I did this after a shower sometimes. The top photos show black stuff on my hands and this is after rubbing along my arms.
Clear crystal debris, fiber balls, black specks, black debris
I've found several of these weird grainy brown things with black dots all through them and clear stem things in the middle.
