It doesn't happen so much anymore, but when I was very young (up until about 8) I used to have these really horrible nightmares about either someone trying to hurt me, or someone raping me. I had one about these shadow people slipping in through the cracks in the doors and windows trying to get me when i was about 4 or 5, and when I was 8 I had one about satan raping me really brutally. This happened all the time, there was a long period of time when I used to sleep with my mother because I was so terrified of being alone in my own bed. I felt like it was cursed or something. Those are gone now for the most part, but now I have this weird shit that happens when i sleep, like I'll wake up but I won't be able to make myself move. Almost like I'm paralyzed or something. It's pretty scary sometimes, and I have to fight really hard to come out of it. Has anyone else here had those really, really bad reoccuring nightmares? I'm so glad I don't have to deal with that shit anymore.
It could be traumas and childhood fears passed on from the parent down onto the child. It sounds like either this has nearly happened, or your mom fears it and it has passed onto you, or you have a serious or subconscious fear of being raped. Also, the shadows raping you could be the fear of outside forces corrupting you; you might have a fear that's manifested itself into your subconscious. I've only had dreams wehre I've shot someone in the head. Those dreams were really frightening, because I don't have a murderous bone in my body.
