A dream about a zebra or zebras can mean that you want to experience more of the world. It could mean you want to travel more, as zebras are usually only found in exotic places, compared to the USA and Europe. If you’re dreaming about zebras and you DO live in a country where they naturally roam free, then it could mean you’re just used to seeing them.
