Running in the woods to a frozen hot tub

I have no idea how the dream started or everything that happened in it, there are only bits and pieces here and there and the more I think about it the more messed up it all seems. The parts I can remember: I was running in the woods, not from something, just running, with two guys who were my friends. One had a dog and I was running in the middle. My path open to this open place where as one stayed somewhere behind and one got in to some place where there were bushes like walls and a fence at the end. I was alone on a path, with a road opening in front and a bigger road going sideways in front of me. I stopped and looked if I could see my friends. Then there was this old VW van, I think it was light blue. I couldn't start it because the guy who had run to the part of the forest that had the walls had the keys. I heard voices and got scared so I hid somewhere that felt like a pile of chopped trees that had been covered with plastic. There was a small piece that I could hide behind, unless someone came from the other side. I saw these two guys kill a girl (everyone around 20-30 years old) with a rusty metal bar (the type you use inside concrete walls when building houses). Then they saw me and I was begging them to spear my life. Suddenly I was in the van with those two guys who were my friends. Suddenly there was a bump in the road and I saw the killed girl fall off the bottom of the van into the ground and there was a huge pile of blood and the dog that had been with us run to the body and started licking the blood. I asked the guys not to look but they did. And looked at me confused but I couldn't tell them anything. Next I sat in front of Facebook, watching my friends list and thinking about whether I should tell my co worker "Alfons" (not any one that's that close to me) that he should not wait for his girlfriend to come home since she's been killed. Then I was in some kind of a hotel room and we had an argument about sex with "A" and I shouted "Well maybe you should change to another pair of wet boxers"... somehow that would help him get his mood on. There was a pile of clean wet white boxers on the couch. Then the idea was to go to the hot tub, on the balcony, and beneath there were people laughing at "A" who couldn't get the ice off our hot tub. It was suddenly winter and "A" sat there with his feet in a frozen hot tub, trying to break the ice. Then we were in a Hotel lobby going somewhere and then at a techno party with some friends who I have not seen in a long time. People were getting a signature in some notebooks, which meant they was getting their VIP passes for the parties to come. When I went to the toilet I asked my friend to grab my coat, but she only took hers and I had to go get mine from the lady at the cloak room, who had made a mess of my coat and her cardigan all wrapped in each other.
