I remember posting about this subject on a similar thread ages ago now, my main answer still hasn't changed since then but I can add another to it.
My most recent dream I can remember was a holiday to some kind of quiet beach, for some reason a lot of people I know were there, as if we had all moved to the same area or done some massive tour group. What made it terrifying though was I became more and more paranoid about meeting up with them as every time I would be alone with one person I would have blackouts, then come to and find out I've just killed them in various slasher horror movie methods beyond my control.
The one nightmare that still sticks in my mind the most however from years ago was when somehow my PC was turned to a bomb, which I shouldn't have been able to disarm but somehow did. Then whoever was responsible for it proceeded to hunt me down I'll assume because he was pissed that I managed to do it, until I was impaled in the back... which resulted in me waking up somehow with my back hurting like hell
