If you dream Big Brother is spying on you using spy drones, this dream interpretation is about self-confidence and personal security.
During your day, do you see evidence of government or others spying on you using drones? If yes, you should take pictures of the flying drone, as evidence. If you don’t see drones or hear them, and there are no spy cameras anywhere in your immediate vicinity, then your suspicions of drones spying you, are unfounded. You maybe too suspicious, or paranoid about being watched. You should have more confidence in yourself. There are no valid reasons for you to fear you’re under scrutiny.
