First Dream

I apologize I haven't posted here since my introduction. I haven't been sleeping much the past few weeks (no nightmares or anything, I'm just a bit of an insomniac). Either I don't sleep, I sleep for about 10 minutes, or I hit a deep sleep and can't remember anything from my dreams. However, this dream did stick out, and I'm wondering what people think it could mean.

There were four of us: two women that I didn't recognize, one guy I didn't recognize, and myself. We were talking to this elderly man who was dressed in strange clothes, possibly from the Medieval era. He told us that we were chosen to be the new generation of heroes to save the world. In order to gain the powers of the past heroes, we had to master riding these special horses. The other three were able to do so with ease, but I was given the most stubborn horse of all. Pure black with a major attitude. I ultimately ended up having to get on him by jumping and grabbing onto him as he ran past me. Once I got on him, he was fine. The four of us transformed into new outfits. I don't recall what the others wore, but suddenly I was in a black suit of armor, the helmet had horns on it, and my shield had a giant cross on it as an emblem. We were then informed that we were now the new heroes and heroines of legend. The women were the heroines of wisdom and courage, the other guy was the hero of valor, and I was the hero of justice. My horse had also changed somewhat, as now its mane and tail were these dark blue flames. We started riding off in a 1-2-1 formation to what I assume was our first heroic mission. However, before we got there, my horse became a bit wild again and took off in a separate direction. He suddenly stopped and I lost my grip, so I ended up being thrown from him. I crashed head first into a tree, and then I woke up.

Any possible translations?
