An Acheri is the ghost or spirit of a little girl who was either murdered or abused and left to die. She comes down from mountains and hilltops at night to bring sickness to humans, particularly children. They are often depicted with dark or unnatural eyes and can also be referred to as "hill fairies". The only defense against an Acheri was thought to be a red ribbon tied around one's neck. The Acheri is said to bring death to the elderly or other people with low immune system defenses.The Acheri is from the mythology of India, but some sources mistakenly attribute them to Native American folklore. * Referenced from Wikipedia under the Creative Commons license.
