I used to have reoccurring dreams of elevators.
Whenever I got in one something would go wrong.
I eventually linked these dreams to a behavior I had and the beliefs surrounding it. The whole thing made me feel totally lacking control. Just like being stuck in an elevator that's not acting right.
I really do not know what your dream is trying to tell you.
The only thing I can think of is maybe you know someone with an "explosive" temper?
