sometimes a camel is a symbol for a journey, sometimes sad and sometimes a large and healthy person, depending on the circumstance. The same applies if a big camel seen.
an unknown camel:
If an ugly camel in an unfamiliar area, a city or a village does appear, it means that his enemies will make his appearance at that place or that place floods, pests or diseases will be destroyed. But if the camel which appears beautiful and healthy, the end result of these disasters are good and a means of blessing.
