Parallel universes, surreal sequences, and impossible feats are possible in dreams. Dreams can make anything possible, even exploits you never imagined. They can, however, be very cryptic and strange. Why are some dreams pleasant and some disturbing? Dreams do exist to serve a purpose. Dreams occur in order to help organize the dreamer’s thoughts and emotions. Certain objects may serve as symbols for a more complex, metaphoric meaning in a dream. It has been reported that people who undergo much stress often dream about losing their teeth. The stress in their life translates into their dreams as their teeth fall out; giving the dream a sense of desperation and fear. The dream may not explicitly reveal that the dreamer is stressed in real life, but under further observation the dreamer may recognize traits in their dreams that are present in their waking life. For example the feeling of desperation occurs both when the teeth fall out and in daily situations involving much stress. Similarly, many people often have dreams in which a deceased love one will visit them. The dreamer may have been having trouble dealing with the death, or they may simply be reflecting on their new environment excluding their loved one. These dreams exist in order to help the individual come to terms with the experience and move on positively. Dreamers may also experience the sensation of being conscience during their dreams. Maybe they are playing a sport, or dealing with a confrontation and are consciously aware of their actions and words. These dreams are called lucid dreams and are also positive to the dreamer. The dreamer utilizes the conscious time in their dreams to better themselves in different scenarios. Professional athletes have reportedly used lucid dreams to practice their swim strokes or tennis swings; even auditors and singers report practicing their lines in dreams. Ultimately dreams exist in order to help the dreamer become aware of their emotional state and better understand how it relates to waking life.
