Detailed explanation-1: -REM sleep happens about an hour to an hour and a half after falling asleep. REM sleep is when you tend to have vivid dreams.
Detailed explanation-2: -Rapid eye movement (REM) sleep, or stage R, usually starts about 90 minutes after you fall asleep. Brain activity increases, your eyes dart around quickly, and your pulse, blood pressure, and breathing speed up. This is also when you do most of your dreaming.
Detailed explanation-3: -A majority of your dreams take place during REM sleep. However, REM is not the only stage in which dreams occur-that’s actually a common myth about sleep. That said, the dreams you experience in REM sleep are usually more vivid than non-REM sleep dreams.
Detailed explanation-4: -But during REM sleep, the thalamus is active, sending the cortex images, sounds, and other sensations that fill our dreams. The pineal gland, located within the brain’s two hemispheres, receives signals from the SCN and increases production of the hormone melatonin, which helps put you to sleep once the lights go down.
