What happens to the brain during sleep and dreaming?
The whole brain is active during dreams, from the brain stem to the cortex. Most dreams occur during REM (rapid eye movement) sleep. This is part of the sleep-wake cycle and is controlled by the reticular activating system whose circuits run from the brain stem through the thalamus to the cortex.
How does dreams affect your brain?
At the same time, key emotional and memory-related structures of the brain are reactivated during REM sleep as we dream. This means that emotional memory reactivation is occurring in a brain free of a key stress chemical, which allows us to re-process upsetting memories in a safer, calmer environment.
Is dreaming good for the brain?
New research shows that dreaming actually serves a number of important functions, especially for learning and memory.

The phase of sleep is called rapid eye movement sleep, or REM sleep. New research, published today in the journal Nature Communications, shows brain activity during the dreaming phase of sleep is remarkably similar to brain activity when we’re awake and processing new visual images, suggesting
