Dream About Yellow Halloween Party And Chasing Friend Turned Enemy

Everything in my vision was a shade of yellow in this dream. Mom drove me to school for a Halloween party. I got there and I partied with friends and played card games. Then I explored the new school again and tried to find the bathroom. There was a bathroom sign, but no bathroom. I found it and there was no toilets or stalls. Then a girl followed me into the bathroom with a knife. She threw it sloppy at me and ran. The knife missed and I chased after her. She was 6 feet away from me and I tackled her down. She took off her mask and it was a friend that was a boy. A cop arrested him and the the friend said "I will kill you Kyle!" Even though my name is Exeller. I ran too the car with my mom and my brother inside. I got in and my mom asked "how was school today?" I explained everything and they joked about it. We got home, I went into my room and saw two turret guns. I closed the door and protected myself.
