In employing the religious symbol of "cloisters" Coleridge effectively communicates the narrator's loneliness. In a religious context, a cloister refers to a place of religious confinement, free from external influence. Thus, Coleridge communicates that similarly, the protagonist was isolated - in his instance, from companions. The favourable contrast of the narrator's birthplace to his school also demonstrates his loneliness. His birthplace provides a variety of engaging sounds and sights - bells, fairs and a diverse landscape. Alternatively, only the "stars and sky" are engaging within the city. Hence, Coleridge articulates the depravation the protagonist feels within the city, his isolation from natural beauty and thus, his loneliness.
The ability to gain insight from imaginative journeys is another theme expressed in "Frost at Midnight." Through his meditation, or speculation, the protagonist gains an appreciation of the power and beauty of nature. Contrast is employed extensively; whilst the narrator's babe shall "wander" amongst nature, he was "pent" within the city and his school. This infers that nature has the power to liberate one's soul, while a city traps and confines a person. Similarly, the natural world is described extensively, revealing immense variety, whilst the city only offers the "stars and sky." In this way, Coleridge expresses that the natural worlds is far more beautiful and stimulating than the city.
George Lucas" film, "Star Wars," also presents an insight, or moral, as a result of an imaginative journey. This insight focuses upon the motivation for journey. Lucas suggests that journeys should not be undertaken for materialistic motives, but focus upon values such as trust and friendship. This is communicated simply through characterisation. When first introduced to Han Solo, he is an extremely materialistic man. However, through the course of the journey, he ultimately relinquishes these values and focuses upon his companions and common gain, helping to thwart a murderous regime.
