Black Eyed Children are an idiosyncratic phenomena involving eerie kids with ghostly pale white skin and pitch black eyes going around asking their victim for seemingly harmless favors. Usually these involve asking the person if they can come into the location that the person is at like a house or a car. Because they usually have to be invited to come inside, some have speculated that the Black Eyed Kids are vampires because their validation is limited. Some even have said that the Black Eyed Children are regular children who've been demonically possessed or human/alien hybrids.
What ever the case may be, when the person is in their presence they often describe an intense amount of fear and dread. They've even described being in an almost catatonic hypnotic state when they look into their midnight eyes. Most of these children are usually always between the ages of 6 and 16.
The supposed origin of the legend are 1998 postings written by Texas reporter Brian Bethel on a "ghost-related mailing list" relating alleged encounters with "black eyed kids" in Abilene, Texas and Portland, Oregon. Called classic examples of creepypasta, Bethel's stories gained such popularity that he published a FAQ "just to keep up with demand for more info about the new urban legend." In 2012, Brian Bethel told his story on the reality television series Monsters and Mysteries in America. He wrote a follow up article for the Abilene Reporter News, describing his experience.
Some cases of Black Eyed Children could be pranksters wearing contact lenses, or children with aniridia.
