Zoos in real life are connected with nature and wildlife, and so in dreams can signify our natural, savage side, our animal instincts or raw primal urges.
Dreaming of animals in a zoo can also reflect a need to step back and observe our animal cousins and their much simpler style of living, say when our day to day lives seem to be getting on top of us and out of control.
Zoos in dreams are also connected with chaos and being out of control, a cacophony of sounds and babble.
If your zoo dream doesn’t focus on any particular animals and is just a wild mixture of noisy animals, it could reflect a need for peace and quiet if the dream is unpleasant.
Or, if you enjoy the feelings attached to the dreams, it could be that you want more variety and color in your life.
