I have this classmate. Our friendship has weakened over time due to certain events that I'd rather keep personal. Upon my observation, he seems to have a history of where he could have spirits trapped in his head. To explain it better, I think it's something from his subconscious awakening. I was sitting beside him and he kept mumbling wildly to himself. He's had insomnia for quite awhile. And he's been limping recently. He kept saying things like,"She is watching." and "I've prayed to the goddess." When I confronted him about this goddess, he shook his head in a disapproving manner which leads me to think that either he has no faith in this goddess or this goddess is not of good nature. I've tried to get him to tell me what going on with him, but I can barely gather bits and pieces of what he's saying. Plus, he's most likely lying. I've recently found out that he has begun to distrust me. I'm not sure why. I only want to help him regain his sanity. If you need more insight, please mail me, for I wish not to explain these details out in the open.
May Odin be with you and blessed be.
