To have been dreaming of a big bang, aka dreaming of explosion, is bad news. You probably had a bad situation during your waking day and this theme was brought into your dream. You might like to reflect on what was the troublesome issue that triggered this dream.
On the other hand, a big bang could be the end of an episode, which signals the beginning of a new phase.
Other meanings can point to an event or a matter that has been blown out of proportion. Which explains why there is dream imagery of an explosion with a big bang.
A big bang, which causes a fall back to the ground, can also refer to a wastage of money and resources. Precious materials which are burned in the explosion, means in real life, you are depleted of resources.
A big bang can also hint at a start of a new relationship. It may start in a good, spectacular manner, like as in with a big bang. How it progresses or ends, is up to the two of you to work it out.
Dreaming of big bangs can also mean gun shots.
