Explanation:
Most dreaming occurs during REM (rapid eye movement) sleep, which we cycle through periodically during the night. Sleep studies show our brainwaves are almost as active during REM cycles as they are when we're awake. ... Because if the brainstem is injured, patients dream but don't go into REM sleep.
Answer:
=> Sleep happens in cycles. Each complete sleep cycle takes about 90 to 110 minutes.
=> Most dreams happen during a phase known as rapid eye movement (REM) sleep. The first REM sleep period usually occurs around 70 to 90 minutes after we fall asleep.
=> During this phase, an amino acid known as glycine is released from the brain stem onto the motor neurons. These motor neurons conduct impulses outward from the brain or spinal cord.
=> One study has suggested that dreaming can happen during both REM and non-REM (NREM) sleep, but that different physiological processes underlie the dreaming at each stage.
=> The dreams that occur during these periods may differ significantlyTrusted Source in both quality and quantity and probably result from different processes
