If you are suffering from personality disorders, you are sometimes not yourself, if people talk about you as being abnormal or disturbed, then it's very likely that you can be helped. Personality disorders appear most frequently when our problem is spirit attachment. We have to take into account that the spirit which finds itself inside our body has a completely different personality. According to the strength of the spirit, that personality will manifest itself in our behavior more or less frequently. That is why personality disorders are such a common symptom of possession.

A person who till then has been active, sociable, cheerful may suddenly become closed in on themselves, it may be hard to make contact with them, they themselves may start to have suicidal thoughts. Or vice versa: a calm person may become aggressive, ready to destroy everything in one moment. Their eyes emanate hatred even towards those they'd love till now. Every case is, of course, different. In some cases, a person is himself for a moment, then somebody completely different, and then himself again. The moments when he is “somebody else” are not noticed by the possessed person, nor indeed remembered. Other times the sick person is someone completely different constantly, and only very rarely themselves. This happens when the body and the mind are surrendered to the will of many different spirits.
