A Makuragaeshi is a "cousin" of the Zashiki-Warashi and the Usutsuki Warashi but is neither benevolent nor malicious, instead they are seen as mischief-prone tricksters who love to steal pillows during the hours of night and place them in awkward or inappropriate places.
They may also run around the home, leaving dirty footprints all over the floor and scare residents with creepy sounds, at their more dangerous they can induce nightmares and sleep paralysis but this is relatively rare.
