This dream may symbolize a hidden aspect of your subconscious that is trying to reveal itself to you. The upstairs location of the dream suggests a higher level of consciousness, while the safe represents a locked away part of your mind. The fact that it is located in your aunt’s old home could suggest a connection to your family or past experiences. The presence of your dog, a symbol of loyalty and protection, could indicate that this hidden aspect is trying to protect you. However, the closing of the safe’s door could suggest that you are not ready to face this aspect yet. The act of calling the police could represent a desire for outside help or guidance in understanding this hidden part of yourself. Overall, this dream may be urging you to explore and confront a part of yourself that you have been avoiding or suppressing. It may be time to unlock the safe and discover what lies within.
