Rajkumar (Raj) Dasgupta, an assistant professor of clinical medicine at the University of Southern California's Keck School of Medicine, who's also part of the AASM, tells Elite Daily in a phone interview.

'REM sleep is one of the most important stages of sleep because it rejuvenates the body, mind, and helps out with your memory and health,' Dr.

In REM sleep, per the AASM's breakdown, your breathing picks up, your eyes flutter beneath your eyelids, your body moves into a deep sleep, and it's also when your brain activity is heightened enough for you to experience vivid dreams. The last two stages are when REM (rapid eye movement) sleep happens. The first two stages involve light sleep and slow brain waves (like the kind of sleep you get during a quick catnap), and the third stage is when you're the most 'out of it' - aka when it’s the hardest to be woken up from your slumber. According to the American Academy of Sleep Medicine (AASM), there are five stages of sleep, which repeat throughout the night about every 90 to 110 minutes. To tackle this question, it's important to understand what's actually happening in your brain and body when you're sleeping. As with most things in the sleep world, though, it's just a little bit complicated. If you were dreaming then you must’ve been sleeping soundly, right? So does dreaming mean you’re getting good sleep? Or does it mean you went on an excellent adventure at the expense of your beauty rest? Well, there's not exactly a straightforward answer, but there is an explanation for both sides of the debate. It’s almost like your dreams kept you up all night. You were tossing and turning all night, and you remember the dream you had so vividly, as if it really happened.
