What happens when you scream in your sleep?

Screaming in your sleep, often referred to as sleep talking or sleep terrors, typically occurs during deep sleep stages, particularly in non-REM sleep. It can be triggered by stress, sleep deprivation, or certain sleep disorders. While it may disturb your sleep and that of others, it usually doesn't indicate a serious medical condition. In most cases, individuals are unaware of their actions and won't remember the episode upon waking.
