Makuragaeshi information

The makuragaeshi (枕返し or 反枕, pillow flip) is a Japanese yōkai. They would come at night to one's pillow side and flip over the pillow. They are also considered to change which direction one's head or feet are facing. They are often found in many actual stories from the Edo Period to the modern period, and they are often said to appear as a small child or a bōzu, but there are no clear-cut accounts of how they look. In the Edo Period collection of yōkai pictures, the Gazu Hyakki Yagyō, they are depicted as a miniature Niō.^[1]
