Dreaming of a zoo can be a sign of confinement. The animals inside a zoo are all kept behind bars, making sure they can’t interact with people and keeping them locked up. Thus, dreaming of a zoo can be a reflection of your own personal life. Perhaps you are being confined, not necessarily physically but emotionally.
Alternatively, this dream of being at a zoo is indicative of you feeling like you are placed under observation and scrutiny. People come to the zoo to monitor your actions and observe your appearance. Therefore, a dream of being at the zoo is symbolic of your self consciousness. You hate being there for all to see and worried about what to do with so many people.Guide and Resources on Zoo in Dreams
