I dreamed last night that I killed someone.

Dreaming of suicide is a common nightmare, but it usually doesn't mean that you really want to kill or have a tendency to kill. This kind of dream is usually the embodiment of emotional and mental stress, which may mean that you have encountered setbacks or difficulties in your life, psychological anxiety and depression. You need to find some ways to relieve your emotions and stress.

In addition, this dream may also symbolize that you need to change or end some relationships or behaviors. Or to some extent, you control some of your inner impulses or desires, hoping to gain more freedom and control. Anyway, I suggest that you don't worry too much about this dream, and try to find some ways to adjust your emotions and relieve stress, such as exercise, meditation or seeking professional psychological counseling.
