Dreams involving violence or extreme scenarios, such as being part of a group of serial killers, can be quite unsettling. Such dreams may reflect feelings of powerlessness or fear in your waking life, coupled with a desire to take control or assert dominance in situations that seem overwhelming.

The act of joining the killers and finding enjoyment in it may symbolize a conflict within yourself—perhaps there are aspects of your personality or emotions you are struggling to accept or integrate. It could also indicate a release of pent-up frustration or anger that you may be feeling in your daily life.

Consider reflecting on any current situations or emotions that may be causing you stress or anxiety. It might also be helpful to explore creative outlets for expressing these feelings in a healthier way. If this dream continues to trouble you, talking to someone about it could provide additional insights and support.
