Poltergeist
Poltergeists were troublesome , haunting ghosts or spirits, notorious for moving or destroying objects, making noises and disturbing people.They were able to levitate and interact with objects, cause knocking sounds, even hit or bite living creatures and men and generally cause uproar and confusion.
In their origin such ghosts had mostly originally been the Fëar of Elves or Orcs who , out of fear of punishment for evil deeds, refused to enter the Halls of Mandos and instead fled and became lawless and unbound haunts, often wandering or sometimes bound to a specific place.Most of these Ghosts suffered dearly from their miserable residual-existence and were quite distraught, confused or even completely insane.Elves knew these unruly ghosts as Úlath lhain (S."Wild Ghosts") or Bruiyl (S."Noisy ghosts, Poltergeists") ,Orcs as Gogoli (Orc."Poltergeists"). Rarely also spirits of mortal men could become Poltergeists, but this was uncommon since their spirits had to be bound to the Matter of Arda by some greater power, and even so, their ultimate departure to the Timeless Halls was only delayed.In any way these mortal ghosts were not really free in contrast to the ghosts of immortals.
