Oh, that's from my favorite scary story! In the full version as I heard it, a woman is repeatedly waking in the middle of a spooky night by a strange dripping sound from the bathroom, but calmed each time by her dog licking her hand from where he sleeps under her bed. Then, the third time, she goes to the bathroom to check on the noise, and sees her dog's butchered corpse in the sink, it's blood dripping to the floor. And written in its blood on the bathroom mirror are the words "People can lick too, you know"

It is only natural for creator beings to visit their realm and it's inhabitans from time to time.
