Dreaming of nuclear war or a nuclear bomb represents feelings of total destruction. There may be an area in your waking life in which you are going through a transformation – a part of you needs to be [metaphorically] destroyed so that you can make space for new growth and new opportunities in your life. Alternatively, a nuclear bomb or nuclear war could represent the continuing after effects of a particularly traumatic event in your life. Even though the initial shock has passed, the consequences are very real and can be just as bad as the initial event.
