Have you ever had a reoccurring nightmare? What was it?

I would be standing in a dark stone castle. The grey walls would be lined with tapestries, torches, and suits or armor. I would start to walk through the halls. Turning left here, right there, or continuing straight. I always walked a different way through the castle each time. The torches would flicker on the walls and my shadow would dance behind me on the floor. Eventually I would hear echoing footsteps behind me. I would stop, turn around, and no one would be in sight. Just a suit of armor standing next to the wall. I would continue walking, thinking nothing of it. Then, I would hear the footsteps again. Clang, clang, clang. I would halt and turn around as fast as I could, and again, the only thing in my sight would be a single black suit of armor standing against the wall. At this point, I would start to get really nervous and walk faster. And as soon as I had gone a few steps, the footsteps would start again. Clang, clang, clang. I would start to run, turning down corridors and just running as fast as I could. The footsteps never got faster or slower, just the same beat. Eventually, in every dream, I would find myself in a large empty room. After I entered it, I would realize with horror that there was no other exit. Then I would whirl around to leave the way I came in, and the black suit of armor would be standing in the doorway blocking my exit. At this point I would wake up. It was such a weird and scary dream.
