Mansion and Cat Killing ...

I dreamt at first I was in a mansion like place. There were obnoxious kids running around, one at one time got into a bag of some kind with a bottle of whiskey and got drunk. I don't know my place there nor the situation, but my late brother was there, I think the kids were something to do with him (though he died without issue). Then I was driving in my real life car past an apartment complex and I think I was looking to rent there when I saw a cat licking a dead cat. I realised that not only was the cat dead but there were many dead cats around some hung, some just in pieces. I rounded a corner and there were three boys and a bunch of cats running to them and they were killing them as fast as they could catch them. I was horrified and started to call the police on the cell phone and they stopped and started to nonchalantly walk off, past my car, looking in. One was just hateful, covered in blood and they passed my car, then he came back and looked in with pure hate on his face and suddenly overturned my car. It frightened me but I was glad he did it because then there was something more serious for the police to charge him with. I was calling the police, the two other boys were asking him why he did that, then I woke up.
