Bad slayer concert

From 2 or 3 nights ago

I was at a Slayer concert with someone. I can't remember why, but I just remember it being quite bad in some way, however I thought it was good still. It was very violent and packed, and it was some sort of festival as it was outside, and it was pitch black and dark at night. After the concert, I went back to my house. For some reason, my house was my nans house. Last year she bought a new house, however in the dream it was the old one. I walked in and the living room was right in front of me. Normally you'd have to walk through the kitchen and the hallway first. My Dad asked me how the concert was, but didn't seem very interested. I told him it was great, however I told him the down sides. I felt the same way I imagine my sister had felt when she went to an Airbourne concert. She enjoyed it, but it was just too crowded and rowdy.
Then, I was on MSN with my friend Ryan. He invited me to a sleepover with him, Connor, Daniel and Alex. They are all my friends, but not in my regular friend group. They are slightly chavvy and they don't hang round with me, which is why I was suprised they invited me. I explained that I wanted to, however I was already going to Matt's (which I went to yesterday). Ryan said okay, and that was the end of the conversation.

There was also something to do with the water slide scene in the malcolm in the middle episode at the waterpark, but all I remember was a playback of the scene.
