Since I was a little kid, from my very first memories, I've ALWAYS had nightmares, consistently, like, 4 or 5 nights a week. I'm 20 now, and this is still continuing. I find it happens less when I sleep with my boyfriend, and if it does happen then, at least I'm comforted when I wake up.
The nightmares themselves are disturbing. Most of them, involve my family trying to kill me. I have no idea why. My family is wonderful. My brother and parents have never been anything but kind and supportive towards me. Or, some of the nightmares, start out normal, and then all of a sudden, it's dark, and everyone's gone, and that's when I know that I need to get out.
The oldest one I can remember was when I was about 6 or 7. I was running through a field, with friends, running from something. And I tripped, and no one stopped to help me. I looked up into the night sky and saw a glowing green face, and then I woke up.
Nowadays, it's mostly like I said before: people trying to kill me. I'm not sure if this is some kind of deep-rooted subconscious trust issue that I have, but it's very disturbing. I've only told my boyfriend the details of my nightmares, since I've woken him up by punching walls and pillows before and flailing about.
I read one time about "lucid dreaming", which is where you realize that you're dreaming, and can control your dream from that point. This only worked for me once, and since then, I've tried it, and the nightmares have continued. Luckily, I've gotten good at waking myself up from them. I feel like I might need to talk to a therapist about this, and hope that they know more than I do. I've lost a lot of sleep this past summer due to this.
