dream -

Dreams are subconscious experiences that involve sight, hearing, thoughts, feelings, or other senses in sleep, especially during sleep accompanied by rapid eye movement (REM sleep).

Occurrences in dreams are usually impossible in the real world, and beyond the power of the dreamer. The exception is in the dream that is called lucid dreaming. In such a dream, the dreamer realizes that he is dreaming while the dream is still going on, and is sometimes able to change the environment in his dream and control some aspects of the dream.

Dreamers can also feel emotions when dreaming, such as the fear of emotion in a nightmare. A subject which studies about dreams is called oneirologi.

Dreams occur at the stage of eye movement during sleep, where the activity of the brain is high and as if in a state of awakening. The length of the dream varies, at least a few seconds, or about 20-30 minutes.

Opinions about the meaning of dreams vary by time and culture. Most Freud fans agree with the meaning of vision in a dream is a vision of hidden desires and emotions. Several other theories suggest that dreams are the stage of memory formation, problem solving, or simply the product of brain activation.
