Seeing a murder in your dream typically reflects deep emotions or mental stress. If you dream of committing murder, it may signify genuine remorse for your sins or mistakes. This dream can serve as a prompt for you to pay attention to certain aspects of your life and recognize the need for change. Experiencing such dreams might also be a signal for you to improve your mental state.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Murder" (page 297) â resolved via the equivalent "Killing" entry.
Killing in a dream represents a major sin. If one kills himself, or commits suicide in fear of the consequences of his sins in a dream, it means that he is offering true repentance from his sins, though committing suicide is a major sin that will lead its author to eternal sufferings in hell-fire. Killing a human being in a dream means committing an evil and an atrocious sin. On the other hand, committing an outrageous sin, or a conspicuously objectionable act in a dream may mean killing someone. If one is killed in a dream, it means longevity and that he will acquire a great wealth from the one who kills him in the dream. If one kills someone without slaughtering him in a dream, it means that the victim will benefit greatly from his assailant. Slaughtering in a dream means injustice. Killing someone in a dream also means relief from depression, grief, affliction and sorrow. Killing oneself in a dream also means recognition of the value of lost benefits. If one is murdered in a dream and did not know who killed him, it indicates his failure to fulfill his religious duties. If one recognizes his murderer in the dream, then it means triumph over one's enemy. Ifone sees a victim swimming in a pool of blood that is pouring from his jugular veins in the dream, it means that the victim will suffer greatly from the defamation and slander of his assailant. Ifone intention ally commits suicide in a dream, it means that he is a subversive rebel and a disobedient servant of God almighty. Confessing to a murder in a dream means gaining the upper hand. Killing in a dream also could mean that one is missing his prayers, or neglecting them. Killing one's own son in a dream means receiving money. If one dies as a martyr in a dream, it also means profits, fulfillment of a promise, business success, or perhaps that he maybe assassi nated, or drown, or die under a collapsed structure. If the victim in the dream is a witness in court, it means that his testimony will be accepted, or perhaps it could mean that he will enjoy abundance ofblessings in his life. (Also seeFight)
