Activation-synthesis theory: This theory suggests that dreams are a result of random brain activity during REM sleep, which is then synthesized by the brain into coherent stories or images.
Cognitive psychology: This field of psychology focuses on studying mental processes such as perception, attention, memory, and problem-solving, which are also key components in understanding information processing in dreams.
Memory consolidation: The process of transferring newly acquired information from short-term memory to long-term memory during sleep. This process is closely related to the idea of information processing in dreams.
