After party

Couple of hours later I saw somebody walks into the room, I was trying to recognize him but my eyes were blurry. He seems furious, the guy who was with me stopped him and asked "hey, how did you get in and who are you". "If you want to be alive just stay out of my way" the creepy guy said. I was still trying to recognize him but I couldn't, he seems someone whom I know. "Look I don't know who you are so please get out of my house" the guy who was with me said in a very calm way. They kept arguing for a long time and I wasn't able to recognize him and then suddenly I saw his hands were in his pocket and he was trying pull out something from his pocket. IT'S A KNIFE, the same knife I saw in the hands of that man who was trying to kill me before.
