Dreams are a series of images, ideas, emotions, and sensations occurring involuntarily in the mind during certain stages of sleep. The content and purpose of dreams are not fully understood, though they have been a topic of speculation and interest throughout recorded history.

This book gathers the latest research from around the globe in both these fields of study and focuses on such topics as lucid dreaming, dreaming during anaesthesia, elderly suicides and depression in the elderly.
