Dreams have cultural, psychological, spiritual, and physiological meanings. Psychologically, dreams are seen as reflections of the subconscious and modifications of mental schemas during sleep. Physiologically, activation synthesis theory and continual-activation theory propose that dreams result from brain activation and the interpretation of signals during sleep. Dream content often involves illogical scenarios, exaggerated memories, and emotions that help strengthen memory consolidation.
