I perform them in cases of wild
tenants - spirits and possessed by someone else ghosts (schizophrenia).
Basic symptoms of possession are: depression states, seeing or hearing
spirits, talking to them, anxiety, and intense weakness even after a sleep,
memory loss, unconsciousness, and mental problems.
It is impossible to perform exorcism when a ghost
is already taken over by someone else, for example Satanists. Exorcisms are
applied from distance only.
