6 Bizarre Things Your Brain Does While You Sleep

Your Brain Is Still Awake — Part Of It, Anyway

Your brain doesn’t fully switch off when you sleep. During non-REM sleep, the parts that handle movement and sensory input stay active and keep using energy. Meanwhile, the areas involved in thinking and memory quiet down. In deep sleep, the brain even shifts toward a more “awake-like” state, as if parts of the mind stir while the rest stays still. And get this: sometimes one side of your brain goes into sleep mode while the other remains awake. Your brain is basically a nightclub where different rooms close at different times.
