Demonic PossessionWiki info
Those who profess a belief in demonic possession, also referred to as possessive trance disorder, have sometimes ascribed to possession the symptoms associated with physical or mental illnesses, such as hysteria, Tourette syndrome, epilepsy, schizophrenia, conversion disorder or dissociative identity disorder. In its article on Dissociative Identity Disorder, the DSM-5 states, "Possession-form identities in dissociative identity disorder typically manifest as behaviors that appear as if a 'spirit,' supernatural being, or outside person has taken control such that the individual begins speaking or acting in a distinctly different manner. " It is not uncommon to ascribe the experience of sleep paralysis to demonic possession, although it's not a physical or mental illness. The symptoms vary across cultures. Demonic possession is not a valid psychiatric or medical diagnosis recognized by either the DSM-5 or the ICD-10. The DSM-5 indicates that personality states of dissociative identity disorder may be interpreted as possession in some cultures, and instances of spirit possession are often related to traumatic experiences—suggesting that possession experiences may be caused by mental distress. Some have expressed concern that belief in demonic possession can limit access to health care for the mentally ill.  Studies have found that alleged demonic possessions can be related to trauma.
