Does anybody know what this is?

Keep pulling what looks like strands of hair, but are way thicker, from literally everywhere. My hair, my legs, my eyes, my nose, them seem to like to burrow. It was baffling me for a while cuz it was like they were just falling out of nowhere, but upon purchasing a hazmat suit and protective goggles, I took a closer look, and notice they were on my ceiling. Directly over where I was sitting I vacuumed up what looked like knots of hair. Then there were just random groups of them. Has anybody heard of anything like this or seen this before?
