Cheetah
Like any big cat it can be an attacking force or a wonderful strength. If you are frightened of it then it will seem as if it is attacking you. But if you realise that nothing can husrt you in your dream and you are not frightened then it becomes an aid. See Do you imagine that is a real creature
Also our dream animals are most likely an expression of our own animal nature. See Mammal Brain – Facing Fear
