PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -There are two types of sleep, non-rapid eye-movement (NREM) sleep and rapid eye-movement (REM) sleep. NREM sleep is divided into stages 1, 2, 3, and 4, representing a continuum of relative depth. Each has unique characteristics including variations in brain wave patterns, eye movements, and muscle tone.

Detailed explanation-2: -While we sleep, our brain cycles through different stages of sleep. Sleep is broadly broken down into four stages-stage N1, N2, N3 and stage R (rapid eye movement sleep or REM).

Detailed explanation-3: -REM stands for rapid eye movement. During REM sleep, your eyes move around rapidly in a range of directions, but don’t send any visual information to your brain. That doesn’t happen during non-REM sleep. First comes non-REM sleep, followed by a shorter period of REM sleep, and then the cycle starts over again.

Detailed explanation-4: -Our sleep is made up of 2 types of sleep: Non-REM (Rapid Eye Movement) sleep, which is where our brain is quieter and slows down. REM (Rapid Eye Movement) sleep where the brain is more active and we are more inclined to dream.
