Is it normal to dream about masturbating animals?

I keep having this dream where I'm jacking off my dog charlie, he likes it but then the cops bust in with rifles and smack me upside the head. Charlie starts to talk about how I didn't do anything wrong and then the cops come back and we all smoke some pot together and charlie starts to get really weird when he's pulling the cones. He starts to froth at the mouth and then pulls out these two stones that he refers to as the 'king rocks' and bangs them together. We all then end up inside some kind of helicopter and make out with each other until charlie can't breath anymore. It then loops until I wake up, can someone who knows something about dreams decode this for me? It's really strange
