Murder in a dream often means no emotion in life and no life opportunities. It may also mean that you cannot control your emotions.

On a spiritual level, although murder does not represent a true mortal danger, it is a wake-up call.
It does not matter here whether you are committing the murder or you were committed to it, as it always means that some part of your personality has been separated by force.
This can refer to unused abilities as well as relationships with people. If you are depressed, your murderous dreams may appear more often because it helps you understand yourself better.
Murder and murderer can also mean deliberate destruction.
