Pariodelia is the phenomenon where we take random objects and our brain finds faces or familiar objects to help us understand it. Survival instincts want us to know where other living creatures are around us, and recognize their face to determine if we are in danger or not.
The image above is clearly some blue blankets with rolls of paper towels on top, but our caveman brains see the face of Cookie Monster, and thus access that we are safe.
Unless you have cookies, then you are in grave danger. He is a monster after all.
