Detailed explanation-2: -These four sleep stages are called non-rapid eye movement (non-REM) sleep, and its most prominent feature is the slow-wave (stage IV) sleep. It is most difficult to awaken people from slow-wave sleep; hence it is considered to be the deepest stage of sleep.

Detailed explanation-3: -Stage 4 REM, known as paradoxical sleep, is when the body’s immobilized and dreams occur. Each sleep stage has a unique function and role in maintaining your brain’s overall cognitive performance. Some stages are also associated with physical repairs that keep you healthy and get you ready for the next day.

Detailed explanation-4: -Sleepwalking (somnambulism) most often occurs during deep, non-REM sleep (called N3 sleep) early in the night. Sleepwalking is much more common in children and young adults than in older adults.

Detailed explanation-5: -Sleepwalking happens during non-REM (NREM) sleep, usually in stage III of the sleep cycle, which is also known as deep sleep.
