Does the poem by Brianna Hughes called "Life is Filled with Dreams" have any metaphors or poetry things in it?
Life is filled with Dreams, Dreams which give our life meaning and inspire us to change. We dream about change and improvement, we set goals, seemingly impossible goals, goals which challenge us ...
This is a short quotation from the excerpt you ask about. It appears in her novel Blood Ties (which is rated for adult content). In terms of criticism, it is very doubtful that this short excerpt (apparently five lines) can be analyzed as a poem. There is a movement in contemporary poetry to identify short prose adages (not poetry), or other observations, as poetry but this approach has many dissenters.
This particular excerpt is best defined as an adage as it is "expressing a common experience or observation" (Random House Dictionary). In any event, there are one or two poetic techniques used (better to call them literary or rhetorical techniques since there is no poetry here).
"Life is filled with Dreams": This is a cliche (which in literature is not a good technique to use). It was once an idiom (which is some expression often used in general society) that began once sometime long ago as a metaphor. A metaphor is a comparison. This compares goals, aims and aspirations in life that are so vague, so far off, so remote of ever happening to (literal) dreams one has during sleep: Distant aspirations and aims are like dreams.
"dream about": This is another idiom that has a different meaning from the first and is a standard among the many "dream" idioms. Idioms in literature are acceptable but are not original comparisons such as new metaphors are. This idiom means that you (or someone) is conjuring up mental images of someone or something that you like or long for or wish to see (this is rather like daydreaming in class):
dream about someone or something and dream of someone or something: to have mental pictures about someone or something (Cambridge Dictionary of Idioms)
