A "metaphor" is a comparation, but it's made on a more poetic way (if you understand what I'm trying to say.. hehe).
One example would be:
"The clouds on the sky are little pieces of cotton that flows all around"
Another example:
"The river is like a silver ribbon which goes on the earth which is like your long and precious hair"
Well, hope this can help you somehow.
Have a Good Day! ^-^
