单选题 Every dream is a message from your unconscious self, expressed in a code which only you can understand and interpret. The images, colors, moods and terms of your dreams depend upon your culture, upbringing, slang and your own understanding of things and values. Dreaming is like looking into a mirror and seeing yourself with your own eyes. The first dreams which we have after falling asleep often revolve around the day's events. We go through them, sorting out and discarding things we don't need to remember and gaining insight into those we do. Often, we are inspired with suggestions that we can use to remedy the situations that plague us by day. As we progress through the night's dreams, they may take up more fantastic qualities, offering fanciful experiences. These often pleasant images can relieve the stress of the day. But the dream we have just before the awakening often contains information the subconscious mind wants to make known to the conscious. And this information, if remembered, interpreted, and understood, can serve as an important tool in our lives. Depending upon the content, dream can strike us with their peculiarity, or sometimes even their alarming nature. Some dreams haunt us for years, not only because of their persistence, but also primarily because we cannot explain or understand them. Other dreams stand out with the weird mixture of images, emotions and context, which make us remember them for life. Recurring dreams are quite common, and we usually have them when a certain life situation repeats, or we are facing the same problem over and over again. A recurring dream is often a sign of some emotional weakness in our nature which causes us problems over the years. Lucid dreams are rare, but they are all about people's ability to control their dreams. In such a dream, the dreamer becomes consciously aware that she/he is dreaming and is able to use the memory and participate in dream actions and emotions. Lucid dreams are usually enhanced in a sensory and imaginary way, and sometimes can be accompanied by pleasant music. People can learn the techniques of controlling their dreams. Some historic manuscripts and records say that the ability to control dreams helps a person to reach a higher degree of mind development. This is what some Tibetan Buddhists and Islam followers practiced for the purpose of elevation in consciousness.
