Detailed explanation-1: -Dreams can happen during any stage of sleep, but the vivid ones that you remember tend to happen during REM sleep.
Detailed explanation-2: -REM Stage R Phasic REM sleep contains bursts of rapid eye movements, while tonic REM sleep does not. Stage R occurs about 90 minutes after you fall asleep, and is the primary “dreaming” stage of sleep.
Detailed explanation-3: -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-4: -Stage 4: REM Sleep While your brain is aroused with mental activities during REM sleep, the fourth stage of sleep, your voluntary muscles become immobilized. Your brain also uses this time to cement information into memory, making it an important stage for learning.
