Spirit-being

A Spirit-being is, probably, a sub-classification of the spirit classification.

The only only creatures that are known to have been classified as such are Brazilian caipora.

Behind the scenes

 * The excact defination of a "spirit-being" has not been given in canon. It is possible that spirit-beings are sentient and able to communicate with humans, making them the opposite of animal ghosts.
 * If this is true, human ghosts, Poltergeists and Banshees may be other examples of this classification.

Appearances

 * Pottermore (mentioned only)
