Can anyone Interpret my dream?

Okay my best friend and I take swordplay lessons together... and a few nights ago I had a dream that we were in some kind of tree fortress. Then we came upon this Wolf like human saying only one of you may p. (my best friend and i have different uniforms and swords we use for our lessons) next thing i knew my friend had my sword and my uniform on and i was dressed in an all white kimono with dark black hair and a horn on my head. (the character i was plays a dark and evil being in a movie i saw a LONG time ago) then after a fight to the death we were both drew so much blood i collapsed on the floor and he won. Then I woke up thinking whoa. Why did he have MY uniform and sword and why was I the evil one... obviously as I said before that wolf like being said only one may p. He was trying to save some one so thats why he needed to p and when i was collapsed on the floor and saw who he saved I looked at who it was.. it was my other best friend... omg it doesn't make sense...
