Last night I had a very odd random dream, and i would really like it if some people would help me understand it.

So what happened was I was standing in the center of a square gazebo, and in one corner was a man who was masturbating, and in the other corner there was another man with a mouse, and he was sticking the mouse's head in paint and then swinging it's tail around. I ran over to the man and told him to stop doing that to the poor mouse, and he told me that he was trying to poisen it. I yelled for him to stop and give me the mouse, so he handed it to me and went away. i cleaned up the mouse and cleaned the paint off its face. it was a little whiteish grey mouse, and one of it's eyes was damaged from the paint, so he couldnt open it. Also, he could talk, and he thanked me for helping him. I decided to keep him as a pet, and I named him Earl. Then Earl and I were walking around and i looked down to where he was before, but he was gone. I looked around for him and i found him body, and a spider, and somehow i found out that earl was a robot mouse body that was ran by a spider. Then, I stepped on the spider and killed it, and then told Chevy Chase, who suddenly was standing right next to me, that i was to kill the spider.
The end.

Please please please help me figure out what this dream means, i feel like its something i shound know.
Thanks!
