That does not at all sound like a decent dream, and to have it over and over must have been even more unpleasant than the actual dream. Did anything during the day trigger that dream, do you know?
In most recent times, I've had these nightmares where what actually happened in the dream was very repetitive. There would be this man in a long coat, and I would not ever be able to see his face. And he and I would always be in this dark room, on a grey bed- everything was grey, save me, though. He'd abuse me and then shoot me. They were very strange. :/
Another weird dream was also a nightmare, where it was stormy. The room I was in in the dream was pretty dark; only a little bit of blueish light flooded the room. I was on my bed, laying down, and crying from fear and frustration. I tried to get up, but my attempts were futile because of this medicine that I was supposed to take. I'm not so sure. But it felt very real and I was really scared. Especially when I came to realise that it wasn't the meds keeping me in my place, but a kiddish looking clown, dressed in light blue. He only stared down at me from across the room, and it was like he was dragging me towards him, yet he wasn't even moving
at all. He would have been alright had it not been for the look that indicated that something unpleasant was going to happen.
That second dream I can justify, though, so it's not
that strange.
