Deep Sleep: The body is deeply relaxed. This stage is critical for physical recovery and growth. REM (Rapid Eye Movement) Sleep: Brain activity increases, and vivid dreams may occur. Even though the eyes are closed, they move quickly. This stage is essential for memory, learning, and creativity. Awake: It is normal for a person to wake up several times at night.
