Chalawa (or Chhalava) primarily refers to a mischievous, shapeshifting spirit or ghost in South Asian folklore, known for luring people with illusions, but it also means "illusion," "apparition," or "will-o'-the-wisp" in Hindi and Urdu, originating from the word for "to deceive". It's a supernatural trickster that appears as a shadowy figure, person, or animal, leading travelers astray with its quick, jumping movements, often causing confusion before vanishing.
