There are several instances where psychological factors can be signs of demonic possession. The psychological signs of a potential possession include a number of symptoms that can often be confused with legitimate signs of mental disorders and illnesses. It will be up to the demonologist to assess every situation on a case by case basis to determine whether or not the symptoms someone is displaying are related to a mental disorder or if the symptoms are legitimate signs of demonic possession. When in doubt, a psychological evaluation is recommended whenever possible so that mental illness can be ruled out of the equation.
Common psychological indications of possession include, but are not limited to alterations to one’s social behaviors and activities, noticeable or striking changes in one’s behaviors and personality, and the presence of sleep difficulties or continual sleep disturbances. Possessed individuals may sometimes behave in violent ways and the violence can occur even without any type of provocation.
Supernatural events are common signs of demonic possession and can occur around the individual that is demonically possessed as well. Such events should be verified by scientific investigative means, if it is at all possible to do so. In addition, eye witness testimony can prove amazingly helpful in determining whether or not the symptoms an individual is exhibiting are paranormally related or not, or if the events are indeed indicative of possession.
Additional signs of demonic possession include the appearance of polyglossia, xenoglossia, polyglossic vocals, prognostication, glossolalia, retrocognition, the extensive use of profanities, aversions to objects considered religiously sacred, confusion, and amnesia. A possessed individual might also have auditory or olfactory responses produced from unidentified sources. A quick view of some of the symptoms associated with possession immediately reveal that several of the symptoms including the use of excessive profanities, auditory experiences, and unexplained olfactory responses are also signs of various mental conditions requiring professional treatment.
There are a number of physical manifestations that can be associated with possession as well. All symptoms should be viewed and considered together before a demonologist can deem someone as possessed and needing spiritually related assistance. Again, it should be duly noted that many of the psychological indications of possession are considered seriously grey areas: areas that can also be affiliated with mental illnesses requiring treatment from a qualified professional. When in doubt on any instance, it is better for the suspected victim to be completely evaluated so that he or she can be treated for any mental disturbances, if present, with the utmost immediacy.
