If you are running from a murder in your dream, it depicts something you feel threatened by in waking life.
If you are the murderer, this may express intense emotional hurt towards someone, typically parents; the murder itself will be a symbol of the killing of the emotional bond or a warning that you are on an emotional ‘knife’s edge’. Dreams in which you kill someone may also point towards an internal conflict, especially if you harbor no ill will towards your dream victim in real life, or indeed if they were a stranger or an animal.
If someone provoked you into killing them in your dream, this may tell you what it is about yourself that you need to kill off. Animals symbolize aspects of your instinctual nature in dreams, so if you killed a cat, dog or any other animal in your dream, ask yourself what that animal represents within you.
If someone is trying to kill you in your dream, your unconscious may be alerting you not to a physical threat but to a real emotional or professional threat that someone poses to you.
If you were unable to identify the dream killer, your unconscious may have been suggesting to you that you are being victimized in waking life by a person, a group or an organization.
Dreams in which you are choking or strangled suggest conflict or indecision, as when you choke on your words. They can also suggest repressed emotions, or emotions or memories struggling to be recognized. Because it is associated with the element of water, drowning indicates a sense of being overwhelmed by difficult emotions or problems.
If the symbol of the guillotine appears in your dream, you may be afraid of losing self-control or of losing contact with a part of yourself or someone you value. The guillotine also represents severance of some kind, so what is it that you need to cut out of your life? If someone is poisoned in your dream, this refers to attitudes, thoughts and behavior patterns that are not good for you.
If you commit suicide in dreams, it may depict a sense of hopelessness; perhaps you have been working too hard lately and haven’t been taking care of your health. Or do you feel a desire to retreat from life’s problems or suffer from feelings of failure? It may also be a sign of repressed anger concerning relationships or business.
If someone else is committing suicide in your dream, this could be a sign that you want them out of your life. [1]
