During sleep, the brain continues processing information, regulating emotions and supporting memory formation.
Brain Never Switches Off
During REM sleep, brain regions involved in imagery and emotion become active, making some dreams feel incredibly vivid.
Why Dreams Feel Real
Falling dreams are common, but scientists have not established one universal explanation for them. They may reflect sensations, stress or ordinary dream activity.

Nightmares can involve intense emotions and may be associated with stress, anxiety, trauma or disrupted sleep.
