Dream About Chasing Head

This dream was about

A middle aged woman started to go down an alley where see saw this disturbing looking head (it looked like Prime Minister Chidulken from SAO). She started to run away and down the street. The head lifted up on 4 spingly spider like legs and went after her, smiling. But it was much faster than her, it was just toying with her, making her think she had a chance. After her, he started killing and destroying everyone else. Suddenly, I was in a hotel or some big business of some sort. I frantically went into a room and locked the door, praying he would skip the room since it was locked. He banged on the door and I was not near strong enough to stop him. It was a mistake. Because I locked the door, he knew to look for some one hiding. When he came in, the room started being destroyed. It was like a presentation room with the white fold up tables and such. The ceiling tiles started coming down along with wires. He found me as soon as the door was flung open. I tried to hide behind the door, but if I would have, it would have crushed me when it flew open. Next I knew, I was playing dead on the ground. Eyes open, pale skin, praying he didn’t realize I was still alive. After that, I mustve fallen asleep because I woke up to heavy thundering rain pouring down on me and all around even though the room was indoors. I thought it should be safe to move around with how much noise the rain was making. I started to move, then my alarm went off on my phone next to me. I scrambled and shut it off quickly. The monster came back on his spindly legs, straight at me. I was playing dead again but once again, I messed up. If I was really dead, the alarm would’ve kept going. Next thing I know, the head is a full blown, fat mans body in a suit. I start stabbing its face as it lays next to me. Through the chin. The eyes, everything on its face. It keeps talking though. The only thing not covered in blood on its face is its mouth and I dont hear words but I know its sinister, mocking me. I keep aiming for its mouth but I couldn’t hit it. I just kept stabbing over and over. All of a sudden, I was Turk (from Scrubs) standing and talking to Carla (his wife) who was laying down in bed. I was making stabbing uppercut motions over and over and then I wondered where I was. It had propelled me somewhere different in time. I was so confused as to where I was. I went to the bedroom mirror and looked at my hands in horror. They were covered in blood like they were but I was no longer there. Was this foreshadowing that I was going to kill Carla?
