Dreams serve an essential function in emotional regulation. Research shows that during REM sleep, the brain processes unresolved emotions and reinforces learning. For instance, if you experience high levels of stress, your dreams might reflect this in symbolic ways—like falling, drowning, or being unprepared for an exam.
Dreams are not always literal, but they do serve as an emotional filter, helping us work through unresolved conflicts. Whether they have "meaning" depends on how you interpret them, but they definitely play a role in cognitive and emotional processing.
