Mold is actually a carcinogen so avoid it. although it's not like a bit of mold will cause cancer. I'd say avoid it, but if there's a bit of mold and it's for one night, there's no real medical consequences
I would not sleep on it! Yeah, it can make you sick even if it is for just one night. Every person is different as far as their immune system but it is not worth taking a risk. If you have that in your home then I would get it out.
Umm, okay thats discusting! I would definately not sleep on it! That could make not only you, but other people sick also. Honestly, I would rather take the floor and a pillow.
