I am in need of some way to frame this, or of some direction to research in. Lately I have become afraid that I do not truly know my boyfriend. He has not behaved out of the ordinary at all, and has no history of any kind of frightening or unusual behavior. He is genuinely the kindest, most supportive person I have ever known. But lately I have these moments when I look at him where I become shot through with fear that something is off. It feels as if something is hiding beneath the surface of his skin, like he's possessed. At these moments I don't know what he's going to do. I feel like he's going to lunge forward and attack me, but of course he never does. I'm just afraid there's something inside of him that's just waiting for the right time. I have no idea how to explain it, its just uncanny. It makes me feel like he's possessed, but I know he's not. I don't know what to do. This is taking a toll on our relationship. I've been avoiding him generally and have been distant when we are together. I have broke down crying to him about this twice, but I can't explain my fear to him and he can't understand it. This fear has been going on for about a month now.

It is worth mentioning that I am just coming out of an 11 month streak of nightmares every night. This fear has been featured in my nightmares and sleep paralysis as well, where I see him being possessed in my dreams or in my room. These specific nightmares started after the fear.

Some other general background information: I'm 20 years old. I have anxiety and frequent anxiety attacks, and I have a handful of phobias (all relating to specific bugs). I also have a persistent fear of cannibalism that causes me to have episodes where I am unable to eat or look at meat. My boyfriend and I have been together for two and a half years, and he is 19 years old.

While my anxiety definitely feels related to this... I have not been able to find any information about people developing fears or phobias around specific loved ones when nothing has caused them. Has anybody heard or read anything about others who experienced a loved one becoming uncanny to them?
