Boggart:

[Chronos]

A type of BOGEY hobgoblin in English folklore that had poltergeist habits. Although, it can be helpful and sociable with some people, the Boggart most often is mischievous, annoying and frightening. Without making a visual appearance, it makes itself known by playing tricks on people, such as pulling off their bedclothes. Sometimes Boggart acts are accompanied by terrible noises or laughter. Boggarts can also be nasty and mean, and have been known to scratch, punch and pinch people, and even snatch and carry them away. They inhabit a house, churchyard or field, or live in another body, such as that of a cat or dog. In some cases, exorcism successfully puts an end to their activities.
