I just had a horrible nightmare. I was with a big group of friends, and I think we were trying to go to a house party. It was winter time, and I needed to change my clothes. For some reason I decided to change my clothes in the shopping mall before we got there. When I went inside the mall, it basically turned into a sewer, where I was chased by two homeless men. I beat them up pretty badly, and instead of leaving them for dead on an embankment beside the highway, I decided to call for help. Some people were supposed to come and pick them up. At that point, my friends were there again, and we ended up back inside the mall, which everyone had decided was haunted. As I was trying to change my clothes in front of everyone, in what looked like a shelter with bunks set up near a lobby area in the mall, a weird mannequin came to life and walked down an escalator. There were a bunch of people, including me, that thought that was really funny. Then a living vacuum cleaner came up the escalator as I was trying to change my underwear in front of everyone. It was really frustrating because the underwear was plastic and didn't have an elastic waist. It looked like the underwear was made from clear plastic, and that was pretty funny and we all made jokes about it. Meanwhile, there was some haunted stuff going on, and some people were stupidly trying to convince everyone that we should turn off all of the lights to help us hide.
