I have a similar problem. There more like short visions instead of nightmares though. Some nights I can consider them nightmare, but only whEN I know I'm asleep. Most of the time I see these short visions just when I'm already in my bed and I close my eyes, on my way to going asleep. I'm not asleep so when ever the visions get really intense I open my eyes and there gone. But when i finally go to sleep I dream, like I said, sometimes they're nightmares, but most of the time they're not. They're just... strange... For example, one of my visions was about me taking this survey, and this guy next to me started going crazy and I noticed he had no left arm. He was looking at me scribbling on the paper yelling "HELP ME!!!" lIKE A CRAZY PERSON and pounced on me, trying to attack me. And my dream, started with me, with a knife in my hand. I sort of lucid dreamed from there so I'm not going to go into details with that one. It got so bad, I developed a bad case of insomnia, that I'm currently recovering from. But still... This might not help, but
