Dreams are successions of images, ideas, emotions and sensations occurring involuntarily in the mind during certain stages of sleep.[1] The content and purpose of dreams are not yet understood, though they have been a topic of speculation and interest throughout recorded history. The scientific study of dreams is known as Oneirology. Scientists believe that everyone dreams, but people will tend to forget them when they naturally pass out of sleep through the traditional sleep cycle.
