Dream about Anubis, an obsidian knife, and life and death...what does it mean?????? PLEASE?

In the dream I saw my friend and her parents at the rodeo. They were walking around at night on some wooden platform things like a deck but a walkway. I was following behind them but then suddenly everything changed and I was standing in my bathroom at home looking into the mirror. My hair was straightened and may have been longer. It seemed to me that i was older and stronger. I looked to the bathroom door which had been left open and saw a guy my age standing there. Where as I thought I was strong he was ALOT stronger, possibly older too. He was shirtless and brawny with black hair and I had the impression of dark eyes. Compared to my fair skin he was tanned. He looked alot like this guy I know, but I can't be sure if it was him because I didn't get a clear look of his face. Anyway he said something in a different language that I didn't fully hear and raised a large black knife into the air. The knife was as long as his forearm and pure black, it looked chipped and very old. I would guess it was made from stone or obsidian. He had both hands on the handle end and he plunged it down and stabbed me. I don't know exactly where it sunk in but I crumpled to the ground and clutched the area beneath my and my right with my left arm. My right hand clutched the corner of the wall as I landed on my knees, there was alot of blood and he stabbed me again. Everything went black and then I opened my eyes and stood up and I was still in the bathroom. Some time had ped and I looked into the mirror. Instead of my reflection i saw the female version of Anubis, egyptian god of death and the underworld. I was annoyed because I thought i'd have a because i didn't know there were females and was releived to see I was still definitely a female down there though I was blue and black. Then I looked at the door and the boy from earlier was gone and Anubis or his twin as standing in his place. Though I knew both were one and the same. He looked at me and I knew he was supposed to care about me, and then he came closer and took my arms and i'm pretty sure we "mated"....then everything went black again and this time I was in my human form again and I was standing with the boy in his human form in my kitchen. I didn't see him but I could feel him standing behind me. Then I saw a boy from school named Matthew appear and attack something with the knife from before because he said it was a demon or something and it had been trying to attack me. Then I woke up. What could this mean?
