There is in the Hmong culture. They are called poj ntxoog. They are souls that have not crossed over or are lost. They live mainly in wooded or abandoned places, and eat warms and insects.Traditionally Asian women have long black hair and are quite slender. Also being skinny meant that they didn't eat enough food and thus ghosts tend to be skinny. White is the colour of death and funeral. All people have to go to hell after death, then go through reincarnation towards a new life. The funeral and ensuing rituals facilitate the process. If there is such thing, the dead's soul is still on earth and called ghost.
