To dream of an implosion represents feelings about some area of your life self-destructing. A situation that is collapsing under the weight of it’s own failure or mistakes. Fears of achievements falling apart. Feelings about the culmination of excessive behavior destroying you or someone else. Success that is too much to handle.
Example: A woman dreamed of seeing a building implode. In waking life she felt that her mother’s bad attitude and nasty behavior were causing her to self-destruct her reputation and ability to carry on healthy relationships.
