Yep! I had a centaur dream last night :D so here it is for your perusal and whatever else
(Yes, it's long, but as a CIA-type in Babylon 5 once said "The details are everything." :P)
Okay, this dream had elements of superheroes and secret government, and I seemed to be in the secret government group. And even that part was like we were at odds with yet another secret government group, like their goal was to take us out. We seemed to be associated with the superhero-types, though I cannot think of more than two instances where that nature came out. I know I was in an informal meeting with others in suits, and I was the one that knew the mapping (figures! lol) I think the discussion had partly to do with some chaotic events taking place for humanity, with the super-types having to do what they could without revealing too much of themselves to the general public. Not that they weren't known, only that they were not well-known and accepted. I suppose there are elements of X-Files, Heroes and X-Men, yet, of the three, I've only ever watched X-Files (X-Men movie was good, but I've only seen the first and that was years ago, while the three minutes I gave Heroes was enough to turn me off to its brutality in short order.)
So, there was this point where we were having to gather up the information we knew and flee our offices before being overrun by the other organization. The Supers (to borrow from The Incredibles, a truly great superhero movie :D) were organized and would be leading the way to wherever it was we were fleeing to. There was some discussion of using a seemingly experimental tube/train system as I remember watching some of the films of the designs. However, nothing was really in place, so maybe that was some other unrelated part of the dream. It had a very German feel to it for design and where it was located, and I'm not entirely sure any of this was taking place in the US. It did not have that kind of 'feel' to it or not for everything.
I know things finally got desperate, and though there was some part with one of the Supers floating above me and another group of them, though she and the rest didn't wear "costumes" or not in the way we identify them within our stories. The news media was there at that event as if we were telling them we were doing something and not to panic, but that bit is really only like an image in my memories. After that, we were on the move, only down, like under the building we were in, into the bowels so to speak.
The rest of the team as well as the few other Supers took off, and I remember having a hard time keeping up. By that point we were into a rather cavernous underground 'hallway', though it really was more like a long cave that had been paved with office-type walls, overhead fluorescent lighting, side corridors and doorways. None of those were important, as we were running the long length of this route. It must have been several miles long, it was that big. And to my eyes, I was looking at it like a map, and seeing the others getting quickly very far away from me. I had to go faster, too. Being human wasn't cutting it. I needed something that was faster.
There was no sense of transformation (I don't think there ever is in these dreams) but I was suddenly able to catch up. That was because I was a centaur. The details of my form didn't come into play until I got fairly close to the others. In the meantime, I was galloping and closing the gap easily. In most of the few centaur dreams I've had, it hasn't been a lucid dream; I was always just along for the ride, so to speak. This time was the same that way. I didn't seem to have as much 'control' other than to go where I needed to and so forth. I could still feel the associated feelings of no longer being human, but it was also a natural feeling, like with those other dreams I've had in this form. It never feels like I shouldn't be one.
As I got closer to the group and to the last quarter of the length for this cavern/hallway, I was joined by another centaur. This one, a male, was the typical Greek personification of a centaur. Black horse half, long curly black hair and beard and seemingly older, though not graying. He was keeping up with me, and we didn't talk until we got to the end of the trip and had to slow to a walk. Then because of our size and our normal walking gait, we were overtaking the walking humans. We got into a minor 'argument' about that, him saying we could slow down to their speed while I said (not verbatim ,but the gist of the following) it wasn't natural for us to try to slow our gait. We'd look silly and would stumble more. He tried it, though, and it was as I had said, though mostly just silly-looking.
I remember the details of my own body at this point and of him. We did not have "full-size" horse halves, instead closer in size to ponies, though not that small either. Just a small horse, I guess. I had a bay coat without so much red, close to the normal brown hair I have. Neither one of us were dressed. Centaurs don't always clothe themselves ;) I know my hooves were black, but I think my tail and mane were brown, but I don't recall that detail all that well.
The dream got away from the centaur part and either faded here, or I transformed back to human and then faded. I never saw my Greek centaur friend again. Maybe he was Chiron? ;)
The rest of the dream went back to more of that weird tube/train transportation system, but just the films of it, and showing the failures of individual carrying systems versus for larger numbers of people. It was done almost like a cartoon, with the people as caricatures of their normal selves. Some of the 'failures' weren't so nice, either, but no blood :P
Okay, that's it in a very large nutshell :D
Halve @ it!
