During which sleep stage do dreams occur?

Correct answer is D) REM (Rapid Eye Movement) stage. Dreams primarily occur during the REM stage of sleep. During this stage, the brain is highly active, similar to wakefulness, while the body experiences temporary paralysis to prevent acting out dreams. REM sleep is crucial for various cognitive functions, including memory consolidation and emotional processing. Understanding the association between dreams and the REM stage is essential in the study of sleep patterns and the diagnosis of sleep-related disorders.
