I was in a back room and heard a noise everyone else was in bed so I thought maybe someone was in the house. 
I was in a back room in our house and everyone else was asleep. I heard a weird crinkling noise and was worried that someone had come in the house.

I did, it turned out to be my cat playing with a play mat the kids left out.
