I was at my grandma's old house where I used to live and in my room (which was bigger than usual) a devil octapus was inside the hand-made closet. It's pink tentacles were swiping around and my brother was trying to stop it and I was shooting at it with a very weak power gun of some sort.
In my dream I was some sort of retired video game character and this had been one of my enemies.
I went to get help and found the Osbournes. Sharon gave me advice and Ozzy gave me a dull knife.
I went back to the house and my brother was in the living room. I asked him why he wasn't upstairs and he showed me a bunch of things he found. I grabbed a sharp stick and went upstairs.
I opened the door of the closet and it was sleeping so I stabbed it to death. My brother held open a garbage bag and I tossed it in there with the stick.
