Everyone dreams. It is estimated that in an average lifetime a person will spend approximately 25 years asleep and experience at least 300,000 dreams, regardless of whether these dreams are recalled on awakening. Researchers believe that babies dream the most, children dream for four or five hours a night and adults for one or two hours. Animals also appear to dream.

Research from the University of Chicago has shown that dreams occur during the rapid eye movement (REM) period of sleep, which occurs for between five and forty minutes every sixty to ninety minutes of sleep. Most people only remember the last dream prior to waking but if they are woken up during earlier dream periods they will recall other dreams.

Unless written down immediately on waking most dreams fade within a few minutes. Dreams usually occur in colour but seldom have smells or taste, and this may be due to the fact that only visual brain neurons fire during REM. Almost all dreams use metaphors to deal with issues in the life of the dreamer, and every event in the dream is believed to have some kind of significance for the person dreaming it.
