A series of images, ideas, emotions, and sensations that happen involuntarily in the mind at the time of sleep are known as dreams. A definite understanding of the content and purpose of dreams is not yet established. They have frequently been a subject of scientific assumption and a focus of philosophical and religious interest.
Although there are several studies on dreams, there is no concrete evidence or explanation on purpose, occurrence, or consistency. The objective of this article is to review available literature on dreams with a specific focus on the character, content, and types of dreams.
