The lesson "The Wonder Called Sleep" talks about the concept of sleep. Sleep is a state of unconscious rest. During this state, our body and mind drift into a state of unconsciousness. When we sleep, our body starts recovering from the tiredness caused by the day’s activities. Several things happen to our body while we are sleeping. Our biological system repairs and rejuvenates, our muscles relax, our heartbeats become slower, our temperature and blood pressure go down, our minds and bodies grow stronger, and we gain more immunity power during our sleep. The ever-active brain also slows down so that we won’t be able to think or act consciously. Moreover, we have dreams.
Dream, an activity of mind, is a series of events, thoughts, images, and sensations that happen in our mind when we are sleeping. Dreams can be probable or improbable in nature, but they can never reveal anything about the future. Dreams are essential because it can help us sleep through the night without disturbances. Also, it can tell a lot about one’s problems.
Though sleep is a common experience, it is filled with wonders and packed with power. The poem "Lights Out" by Edward Thomas describes the concept of sleep at its best. It tells us the experience of falling asleep, and it makes us wonder at the beauty and the mysterious nature of sleep. At the same time, the poem also explains how inevitable the sleep is. Once you are in the border, you cannot refrain yourself from falling asleep.
