The lion is authority. Meeting one was read as a powerful ally or one's own rise; a lion that follows tamely is that power on your side.
Tradition reads the symbol as an omen; psychology reads the same dream as a mirror of your present state. Describe your dream and both readings appear together. Interpret your dream
