00:00Here's the fact.
00:01Why do we dream?
00:02Dreams happen during REM sleep, when your brain is super active, almost like you're awake.
00:07But if we're sleeping, why does the brain need to be active?
00:11One theory says dreams help your brain process memories and emotions, like cleaning up your thoughts.
00:16So, are dreams just brain maintenance?
00:19Maybe not.
00:20Another theory is that dreams let us practice real-life situations, like a safe training ground.
00:25So dreams might be memory cleaners in survival training?
00:28Exactly. And that's why scientists still call dreaming one of sleep's biggest mysteries.
