But some experts believe that dreams aren’t just reflecting what we need to know and remember, they’re actively cataloging it. The brain reactivates and consolidates newly received memories and information tidbits while we sleep, and researchers have seen that this process is directly reflected in the content of our dreams. Dreams help us store memories and the things we’ve learned. The advantages of nighttime dreaming are numerous. But if you’re not sleeping well (not reaching deep sleep or waking up multiple times a night), then you’re missing out on one more essential tool that your brain needs in order to keep you healthy and sharp.Įven though you may not know whether you’re dreaming on a regular basis (we dream at all stages of sleep, not just REM, and don’t necessarily remember all the content), it’s safe to say that if you’re consistently cycling through all four stages of sleep without regular interference (meaning you’re getting a full, restful night’s sleep), then you’re going to reap the benefits of dreams. However, new research has shown us that dreaming actually serves a number of important functions, especially for our learning and memory. Scientists used to think that dreams were just a byproduct of the brain’s nighttime regimen. And we now know that dreaming is an important part of these nocturnal activities. Without any incoming stimulation or thoughts, the brain uses this valuable free time to perform maintenance and admin-cleansing, consolidating memories, and imprinting new information. New research shows that dreaming actually serves a number of important functions, especially for learning and memory.Įven though we think of sleep as “powering down,” our brains are doing anything but that when we get shut-eye.
