Grenade – Dreaming about a grenade can be a pretty dramatic ordeal. Grenades are symbols of war and hatred. They are also symbols of conflict and murder. If you dream about having a grenade thrown at you, it is a symbol that you are about to metaphorically encounter huge obstacles that will be difficult to overcome. If you dream about having a grenade or using it to defend yourself, then the message is almost exactly the same. If you dream about using a grenade on a helpless person, you probably need psychological help. Please see a doctor about your abnormal cravings.
