From a psychological point of view, explain if dreams have any meaning.

There are many different ways that this question can be
approached.  One particular way to do so would be to use the work of Freud, who believed
that dreams are a reflection of our subconsciousness.  The conscious level for Freud is
how individuals operate in society and this is predicated upon repression.  Freud
believed that social acceptance and advancement required repression of the subconscious,
the layer of human identity that might express thoughts and actions that are deemed
inappropriate by society and could be rejected.  Individuals repress these urges or
feelings and the only way that this subconscious can find voice is through dreams, when
the individual's conscious is completely submerged in slumber.  In the end, dreams
become the critical piece in Freud's thought to explain how the individual possesses a
layer of complexity and a condition or part of their own identity that has to be
understood and deciphered in order for human beings to be fully
content.
