I had the same horror dream from about 2 years old to 12. It repeated before sleep walking or when I had fever. It brought the same feelings and had the same motifs every time, and it was looping (I'd get massively scared and the dream would restart and the same sequence of events, quite long, would get to the end again). Sometimes I would get to explore a new motif in more details but this would happen after several repeats of the same old horror.

Characters and scenes looked a bit like they were out of a Disney movie (Aladdin, Pinocchio, I remember the guards from Aladdin and the princess/fairy from Pinocchio), which I guess I watched a lot when I was young.
