Dream of wolves biting people.

Dreams are mostly just fragments of memories. The scene outside the reality is the realization of the wish.

Werewolf: Maybe you once broke into a place and the doorman took a dog out to drive you away.

Three people were killed, which means elimination. Because of the pressure and depressed mood in reality, they will have such a dead dream. Those three people symbolize the people you hate or ignore in reality. They are the people you want to sacrifice in the crisis.
