PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -If a person is awakened during stage 1 of NREM sleep, he or she will often deny having been asleep. Most individual’s deep sleep takes places in the first third of the night. Although dreams may occur in all stages of sleep, they generally happen in stages 3 and 4 of NREM sleep.

Detailed explanation-2: -Stage 3. Stage 3 sleep is also known as N3 or deep sleep, and it is harder to wake someone up if they are in this phase. Muscle tone, pulse, and breathing rate decrease in N3 sleep as the body relaxes even further. The brain activity during this period has an identifiable pattern of what are known as delta waves.

Detailed explanation-3: -NREM Stage 1 The first stage of the sleep cycle is a transition period between wakefulness and sleep. If you awaken someone during this stage, they might report that they were not asleep.

Detailed explanation-4: -This is the lightest stage of sleep and begins when more than 50% of the alpha waves are replaced with low-amplitude mixed-frequency (LAMF) activity. Muscle tone is present in the skeletal muscle, and breathing tends to occur at a regular rate.
