I have a few peeps might find interesting. When I was a child, I was afflicted by demons!!! lol, not really, thats what my mom told me it was. It was actually some intense night terrors I would experience that went on for a few years after a pretty harsh emotional trauma.
Here's a taste.

1. The bottomless pit: Falling, always falling. It was a recurring dream, and each time it became more and more elaborate. At first it was just falling darkness, paralyzing fear but later I began to see other people falling as well. The second to last time I had that dream I met Apollyon the angel of the bottomless pit. He said with a smirk in a jovial sarcastic tone, "hi, I'm Apollyon, would you like to stay here forever?" The next time I had the dream, I was able to stop falling and I left the pit.

2. Stretcher: Connected to the medieval torture device which stretched people apart. I had many torture dreams. As I am stretched, I can feel the pain of my skin tearing, my bones snapping, tendons ripping etc. It is excruciating pain, worse than anything in waking life. I am torn asunder and wake up.

3. My sisters doll: When we were young, my sister had a sour patch doll with blonde hair and blue eyes. It had a little dress and pig-tails with bows. I was joyful when I saw it in the dream as it bounced towards me. The closer it got though, it turned evil. The color changed to dark black, red, purple while the clothes became ratty and ripped. Its eyes turned red and its teeth jagged. It attacked me, eating my face and throat, killing me.

I've had some of the most unique nightmare imagery I've ever heard of and I study dreams as a hobby. At the time, these dreams were literally torture but they give me strength now.
