Zodiac
To see the zodiac in your dream represents the various aspects of your conscious being and how you connect to the universe. Alternatively, the zodiac may appear in a dream to denote the passage of time.
Zero
Zero symbolises nothingness and emptiness. You are experiencing a void in your life. The symbol may also share the same significance as a circle and thus denotes infinity, eternity, completeness, absolute freedom and holiness. Alternatively, the dream forewarns that you are going around in circles and headed nowhere. Perhaps your actions have been counterproductive. It also represents timelessness and the super-conscious.
Zipper
To see a zipper in your dream implies sexuality and sexual innuendos. If you are unzipping, then it indicates that you are opening up. If you are zipping up, then it suggests that you are closing yourself off emotionally. Alternatively, the dream may be a pun that you need to keep your mouth “zipped.” You are talking too much.
Zoo
To dream that you are at a zoo symbolises loss of freedom. Alternatively, a zoo suggests that your abilities and talents are going unnoticed. You or an aspect of your life feels caged in. The zoo may also represent chaos and confusion as implied by the common phrase “this place is a zoo!” You may need to tidy up some situation in your life.
Zoomorphism
To dream that you are changing into the form of an animal indicates that you are becoming less civilized, less restrained and becoming more free and instinctive. You may be expressing your newfound freedom/independence and experiencing a lack of boundaries. Alternatively, taking the form of an animal suggests that your primal desires and/or repressed sexual urges are coming to the surface and needing to be satisfied. Consider also the animal that your turn into.
Zombie
To see or dream that you are a zombie suggests that you are physically and/or emotionally detached from people and situations that are currently surrounding you. You are feeling out of touch. Alternatively, a zombie means that you are feeling dead inside. You are just going through the motions of daily living.
