The first step in recognizing the nature of a ghost is to differentiate between human spirits and the demonic. If the psychokinetic disturbances are scary but relatively mild, the family is probably dealing with a human ghost. If that’s the case, an experienced psychic who can differentiate between human and demonic spirits is the best choice. You can’t call the cops to arrest a ghost, but a psychic, especially one who is experienced in psychic housecleaning can perform blessings and other rituals to encourage the ghost to cross over from its mournful existence on the transitional plane into its proper place in the mainstream sequence of Spirit where it can begin a proper spiritual evolution. Human ghosts don’t require a religious exorcism.
Demonic activity is altogether more severe than a haunting by a human ghost. Demonic hauntings are extremely rare, and in the vast majority of cases, the disturbances are caused by a human ghost. However, people confronted with very powerful, malevolent and violent hauntings may be dealing with demonic entities. Demons and devils, unlike human souls, can never leave their miserable spiritual home. Their natural home is in Hell, and they will do ANYTHING to remain on the transitional plane where they can engage in hauntings rather than go back there. For them, unlike for human ghosts, the transitional plane is full of freedom and comfort. Their natural spiritual home is NOT! If the demonic is involved, the disturbances will demonstrate religious overtones and may be very violent. Although it is possible for an experienced psychic to remove a demonic presence if it has not progressed too far, in these cases, the family should probably consult religious authorities.
