I was walking through the park and then a guy said my grandma died and she didn't in real life. We were all sitting in chairs and he was telling the room who each person was that came. they told me that this lady was her mom but i don't know how her mom would still be alive but she was there, she didn't look like my great grandma but everyone kept telling me she was, they went around the room telling me that this other lady was her sister and some guy was her dad and they went on and on but skipped me. When more people came in, he introduced them to the group and went back to talking about my grandma. I left and walked into her hours with my mom, sisters, and brother. I walked in her bedroom and there was a wax figure laying in it, then i walked into the bathroom and there was a wax guy in the bathtub but there was a guy next to the tub just sitting there, acting fake and he had this really creepy, fake, overly happy, like it looks like it hurts fake happy. I saw him and screamed as loud as i could and ran out of the room. I told my mom we had to get out of there because there was a guy in the bathroom. She didn't believe me until he walked into the doorway. I ran towards the way i came in and my sister was already in the room while i was running towards it. She kept opening and closing the door and kept crying the whole time. I got in the room and she shut the door and locked it. I ran down the stairs and out the door and locked it behind me. I don't know what happened to my family but i don't think they died, i didn't hear anyone scream. I ran into another room and it was a big, open room with a glass wall that showed the staircase and the main office. I don't know where i was, i was in some type of school or something but i never seen it before. I saw the guy and he was now wearing a Scream costume, like from the the movie Scream. He had a knife and everything and the music was even playing like it is when he's chasing the kids in the movie at some points, his theme song. Anyway, I was running and he was stabbing people left and right then i ran into a guy i liked and he started running with me to help me out. I ran through a door and he disappeared but i saw the Scream guy still chasing me. I ran down a staircase and through a doorway and past an office where people were just doing office work and answering phone. I got to the courtyard and i saw another guy dressed in a scream outfit.He stabbed me in the back and i cut his head off with a wrench i magically had, it was strange, i took the wrench and opened it really wide and put his neck inside and closed it and his head just popped off, just like that. The real scream guy ran away and i stayed still. Once he left i started laughing, i didn't really die, it was all a ploy to get the real killer to think i'm dead, the guy who stabbed me didn't die either, he was wearing a fake head. I took all the fake blood packets from under my shirt and i started to get up and help the guy up as well. I don't remember making a plan like that, i didn't even know i wasn't dead until the severed head started talking to me. I helped the guy clean himself up a bit and we walked out the door together. The Scream guy was sleeping upstairs so we slowly walked upstairs and into his room. We slowly lifted his knife from the table and he woke up. He was scared and he didn't have anything to protect him. He didn't have knifes in his house other than his own because he didn't want anyone to come in and stab him with them. I picked up his knife and stabbed him with it and laughed about the irony on it. Then i woke up.
And no, i haven't seen the movie in 3 years so i don't think it's do to that, if anyone was wondering.
I think the part about your grandma dying and then him introducing everyone but you could have to do with you feeling that you've lost something or that you're missing out on something. The lady who was supposed to be your great grandma but didn't look like your great grandma could have to do with you feeling that people are being dishonest with you. The wax figure and the wax guy could also represent dishonesty, because a wax person is a fake representation of a real person. A bathroom is a place where you perform personal actions that you don't want other people to see, so the wax guy in the bathroom could represent something negative or "dirty" that people are hiding - also having to do with dishonesty. You telling your mom you have to get out and her at first not believing it has to do with you needing to get things out in th open. An office or a school is a place where you follow rules, the guys in the Scream outfit with the knives have to do with your feeling repressed or restricted and needing to realease your frustrations. The parts with the fake guy stabbing you and then you stabbing the real Scream guy are about you releasing your frustrations.
