Recently I had this really strange incident with a person I know well:
We had been littlehaving a argument and were on the verge of reconciling, when the other person turned her head in a sudden way and looked me right in the eyes with a real weird look in the eyes that made me think "wow, that person is completely insane".
I interpreted it like that: said person often tries to turn an argument into making me look as if I just had been joking and this looking at me directly in an inquisitive way is part of the tactics (but it never was that scary!)
Now I talked to a friend of mine about it, who asked immediately, if there had been a sudden death in the family. My friends theory was, thar there might have been a third one, ie an entity taking control for a few seconds.
In the room the whole thing happened, I had a scary incident not too long ago with something lurking there around.
How can I tell if it was a possession or rather a slip of the mask revealing the true self?
