On average, we spend about one third of our lives sleeping. During a portion of that time, we are also dreaming. While asleep, we can gain rest and refreshment for our hard day of work. Essentially, dreams are our method of relaxing and letting our minds drift away into a distant world. While dreaming, we can interact with various people, places or things.
Technically speaking, a dream is mass hallucination. A dream is a hallucination that is also a fantastical journey in our sleep that either relieves us of stress or tries to detract us from a certain habit or future happening (better known as a nightmare).
Dreams help us to understand ourselves giving that we know how to interpret them. Interpreting dreams is a very powerful tool. We can find out deep secrets or reveal concealed feelings towards something just by analyzing a dream correctly.
When we think about dreams we must wonder why they occur. There are several explanations for this question. It is a fact that we all must sleep. We constantly go through cycles of sleep and wakefulness. During each cycle, our minds must be active. Obviously when we are awake, we are using our minds for various actions. When we are asleep, it is not as obvious how our minds are at work. To keep our minds active during sleep we must dream.
