Lucid Time!

I can remember I was with S and C. C was a werewolf/lycan, and S had some leather-type armor and a bow and arrow. Apparently we were fighting Medusa in some kind of temple area. It was a large stone crypt-like place, with a lot of columns. There were torches on some of the columns that lit the entire room with an orange-ish glow.
Anyways, I wasn't able to look at Medusa (or I would be turned into stone, obviously) But I was able to hear her footsteps and sort of get a sense of where she was. I had a sense that she was behind me, but I realized I didn't have any kind of weapon. I got angry with my two friends and we traded a couple of remarks before I just decided to do things as best I could.
I grabbed Medusa and held her by the neck, (I had to look up and away from her) and I started ripping off the snakes in her hair. I don't know how this worked, I think she gave in eventually and died.
Strange that I would be dreaming of greek mythology/gods. Never really been into that sort of stuff.
After she was defeated, my friend dream characters faded, and the setting sort of morphed into my kitchen. My father was there, but he was smiling really evil-like, and I think his eyes were either bloodshot or glowing red. I realized that I had to fight him, too.
I remembered my lack of weapon was nearly my downfall in the last fight. I went over to the knife block on the counter and took out the big butcher knife. My dad pulled out his own knife that was really more like a small sword or machete, it was so big.
We fought for awhile, but I dominated him, and I think I disarmed him. He had some sort of back up weapon, another, smaller knife. I can remember at one point we got locked in some strange position where he was holding my knife blade, and I was trying to cut free, but in order to do that, I had to cut off some of my dad's fingers.
It was at this point that Lia entered the dream scene. I couldn't really make her out, but I know she was there. She came in standing in the doorway of the kitchen, but she was floating about two feet above the ground, and was partially transparent. and she told me that I wasn't really fighting my dad, but rather some evil character who had created a manifestation of him.
Knowing that my opponent was not actually my father, I began to fight much more fiercely, and I opened up his stance, and stabbed him in the leg. He knelt down and admitted defeat.
But the one thing that sort of stuck with me, was when I walked past him, I looked at the wound on his leg. There was no blood coming out of it. It was just a sort of narrow red cut into the flesh. I again; don't know why, but that detail just sort of stuck with me.

Another thing I can't stop thinking about why, in my dreams, is my father always portrayed as some evil character? (Well that wasn't a direct portrayal of him, but a poser of some sort.) In real life, I know him to be a bit of a grouch from time to time, but for the most part he's really nice. Maybe it's just some symbolism that I haven't figured out.
