Translated from Edo Tokyo Kaii Hyakumonogatari
It was on the 20th of April, in the Saruo mansion near the vicinity of Bancho. A maid who had been in the service of the mansion for many years made the journey from her sleeping quarters to the bathroom in the dead of night.
Suddenly, something colored pitch-black sprang at her, grabbing her by the head. It was such a fright that the maid fell to the ground unconscious in a mere second. The commotion was so loud that the household staff came flying to the scene, nursing of the poor maid until she was able to return to her senses. Even though it was only moments from when the maid fell until the other arrived, nothing could be seen of the bakemono.
Truly, that pitch-black monster was a Velvet Obake.

That sounds exactly like a dream or something my cousin had, but she said she saw the thing’s eyes and mouth with tiny teeth.
