Cloak

Today I woke up to a horrid sight.
I woke up because I heard something loud talking in the living room.
I assumed it was just Sylph either talking to herself or talking in her sleep, but I went to check it anyway.
Sylph was sitting on the coach next to something that I can only describe as a cloak.
It was just a cloak hanging.
When I approached it, it turned.
It was just that, a cloak, except it had 7 arms sticking out of the inside of it, which was filled with like this black void.
I got scared, if I'm going to be honest.
I turned around, went to my room & locked the door.
Perhaps I'm not used to this kind of thing. At least Sylph is humanoid.
