Freakish Dream (Why do I have so many of these?)

I had a dream. See below.


I was driving a car to camp Wildwood. When I parked, I went into the mess hall. It was about 5 times bigger than normal. I got some food at the buffet table, then went to the checkout that was in a dark corner. "Five dollars, Deah," the ancient cashier said creakily. I opened my little purple purse that I always carry (you know the one) and took out a five dollar bill. Except it wasn't. It was a piece of paper that said:

5 Five Dollars 5
FIVE
5 Five Dollars 5

How odd. But she took it anyway. I walked off to eat at one of the HUGE tables that lined the hall, when I noticed my family eating at one. I walked over to my dad and started yelling at him for filling my purse with fake money. Then the scene changed. I was by myself in a room that had a big sign that said:
WOMEN'S CHANGING ROOM
Next to me there was a door with a sign that said:
MEN'S CHANGING ROOM.
It opened. Then I realised that I was naked. I screamed and ran into an unmarked, pulsating door. Inside of this door was a room full of whirling, glowing, colorful, things. I ran up to a computer screen, realising too late that it was a virtual reality game with advanced technology. I screamed again. My friend Sarah (Hi, Sarah) was in the game with me. The game was called Shopping World. Suddenly the game became real. I was alone in a shopping mall, in a concrete area full of trash, painted garishly with graffiti, and- there were three teenagers in this horrid place. Two boys, one fat, the other too thin to be real. One girl, with canines like fangs. They were all wearing tall cowboy boots. The fat boy reached down to his boots and inserted several white, squishy, cylindrical somethings into small holes in his boots. The thin boy and fanged girl followed his lead. Instantly, the teens started skateboarding around the slanted floor on small race cars. Then without warning, fist the thin boy, then the girl, fell down screaming and writhing in pain. Last of all was the fat boy. His howls were quieter than the rest. He had done this before. I ran, as fast as I could, up the red ramp, the stairs. I ran into the cafeteria, where my family was waiting. My dad was talking to a woman with red hair. This is what I heard: "Those teens were using goat fat implants with garlic. They give you a energy boost, then fill you with unbearable pain. (At this point, I realised that I had left my shoe behind with the Goat-Fat-Teens. But, I thought, I can always buy a new pair. Those ones were too small anyway.)
Than I woke up. I still don't understand my dream.
