One night this woman was sleeping in her bed, and she felt her dog lickin her hand but didnt do anything about it. And the next morning after her shower, she sees written on the mirror, Humans can lick too.
The informant heard this during middle school at a slumber party. It was shared when other scary stories were being told. She says that she never leaves her limbs off the bed.
This is a very scary story because you are in the comfort of your own home and you assume it to be your dog but in actuality is a weird person in your home. I think this legend is possible. Although this is a very creepy thing to happen, it is still plausible. The idea of things being written in a bathroom mirror appears throughout folklore, literature, and movies.
