Sleep Telepathy

This is long story, so here goes...

I have known my fiance for over three years. During this time, she's had a habit of talking in her sleep. I first noticed it a few days after we started to date. I thought she was having a bad dream. The dream was always the same. It would start out good. Something like, "I'm so happy I found you...". It would immediately turn into "You're leaving me? NO!"

She came from an abusive relationship. I won't get into this at this point.

As time went on, her tone would change. Whatever the crisis of the day was, the talking would focus on that. But, if I woke her, she would always tell me that the dream she was having wasn't what she was talking about.

One day, I woke up to get ready for work. I turned on the light to the bathroom. She turned over and told me to turn it off. I turned around and looked at her, completely stunned. She was still asleep when she said it.

As time went on, she began to speak to me at night. The subjects tended to be dreary and sad ones. Fears about our relationship, fears about her ex-husband, etc. I would speak quietly to her about them, and she would respond in kind.

At some point, I stopped speaking and merely thought the answers. Without skipping a beat, the conversation went on. Whatever she said, I would continue the conversation in my head. I could have an actual conversation with her by simply thinking my responses.

This has been going on for about a year. Most of the time, the conversations focus on incredibly bad topics. Some of them have been wide ranging. I have been told that she has secret cameras throughout the house, that there are burglars in the house, that I was too far and should lose weight.

One time, I awoke to this: "hold on... Wait for it... 3...2... 1... Now!". I heard a loud bang in the other room. It was the rocking chair hitting the back wall as one of our cats jumped off of it. Completely shocked, I said, "you can read cat's minds too...?" To which she replied, "Don't be stupid... It's a cat!"

Recently, she has started to claim that demons are in the house. We've watched our share of horror movies, so I've tried to take it with a grain of salt. But the stories get incredibly intense. She told me that the demons were outside the room, then in the room, then over my bed. I was, quite understandably, scared out of my mind. I turned the light on and yelled at her to stop. She turned over, and spoke slowly - "I need your sacrifice in order to open the portal to hell. You are the first and we must die in order to end the world."

Also understandably, this was incredibly silly and I got a little frustrated with the television-like nonsense.

One time, I awoke to a pillow being smashed on my head. As I regained consciousness, I saw her lie back to and begin to sleep-talk to me again. She has also kicked me awake or yelled until I awoke.

I am curious to find out if anyone else has experienced such things. When this first started to happen, I was incredibly excited. As time has gone on, I'm a little scared to go to bed. If she has fallen asleep before I have, I often have to shut the door and sleep on the couch, as I'll never sleep if she talks to me when I lie down.

I have spoken to her about these things in depth. She knows what's going on. I have tried to tell myself that it's not real, but I cannot seem to convince myself. Even if I was imagining it, the conversations are too real and her responses too appropriate to ignore.

Help...?
