To dream of machinery represents mechanical or processed minded thinking. Going about a job or activity without much thought. Making decisions without thinking it through or about why you are making those decisions. Boring pattern thinking.
Negatively, machinery may reflect arrogant or irresponsible thinking that doesn’t consider feelings or that it might be causing damage.
Positively, machinery may reflect a strong ambition and will power. Never giving up and keeping yourself going tirelessly.
If dream machinery is broken it may reflect a need to repair your self-image, confidence or a relationship before you get motivated again. It may also reflect an insensitive opponent or problem that has been stopped.
If dream is rusty it may represent a hard work ethic or tireless ambition that has been neglected for a long time. Something you used to be obsessed with or work hard at that isn’t as interested as it used to be.
Example: A woman dreamed of a thought control reading her mind and informing police about it. In waking life she was living in Nazi Germany under’s Hitler’s rule and having anxiety about her behavior being perfectly complaint or that anything she did may stand out as being against the Nazis. The thought-control machine may have reflected her feelings about the Nazi regime’s intense propaganda usage and repressive controls over freedom making the people completely compliant in an automatic unthinking manner.
