Re: I had a dream!
I'm not a dreamologist, but I do recognize some common themes in your dream. Like at the beginning when your attire was all wrong and your sword was broken. I've had many dreams like that where things just weren't right and couldn't be fixed no matter what I did. I don't know what the purpose of that sense of inadequacy is, but I'm sure it's based on the brain's psychological processes.
It's nice that you used the dream world to reunite with someone you knew in reality. I have dreams so real and vivid about people I know, that I actually write it off as a genuine memory, as though it really happened. And why not? A dream is just a memory of a series of events, just like any other memories.
