The meaning of Wrecking ball in dream | Dream interpretation
Dreams of a wrecking ball signify that you are tearing down an old, outmoded system in order to build up a new structure that is better, stronger and more powerful and effective.
The transformation you are in the midst of is a shock to your system, and this dream is giving you the message to be gentle with yourself as you move through this rite of passage. See Breakdown/Breakthrough Dreams and Wreck.
(Crane) A wrecking ball in a dream represents a message carrier.
If one sees a wrecking ball hitting him in a dream, it means that he will receive a strong message which will be carried by a strong and a merciless emissary.
