What’s in my bathtub?

Last night my boyfriend ran me a bubble bath while I finished cleaning. When I had gotten in it, it was already full and covered in bubbles. While in the bath, I was moving the bubbles and noticed the water was really dark and there were these little black things, I assumed Epsom salts. While he was draining he came in and asked what the black balls were and I told him I thought they were Epsom salts and he said we didn’t have any. So, what is in my bathtub? 🤮 no I wasn’t dirty from cleaning, it was just laundry and dishes
